What is formed when reverse transcriptase is used on a strand of mRNA

Answers

Answer 1

When reverse transcriptase is used on a strand of mRNA, a complementary DNA strand, known as cDNA, is formed.

Reverse transcriptase is an enzyme that can convert RNA into DNA. When it is used on a strand of mRNA, it produces a complementary DNA strand, known as cDNA. This process is called reverse transcription.

The resulting cDNA can then be used for various applications, such as cloning, gene expression analysis, and genome sequencing. It is a useful tool in molecular biology because it allows scientists to study the genetic information of an organism, even if the genomic DNA is not available.

Reverse transcriptase is commonly used in the study of viruses, particularly retroviruses, which have RNA genomes. By using reverse transcriptase to make cDNA from the viral RNA, scientists can study the viral genome and develop treatments or vaccines for viral infections.

What must be true about the number of chromosomes to create fertilized cell?

Answers

In order to create a fertilized cell, the number of chromosomes in the sperm and egg must be equal. This is because during fertilization, the sperm and egg combine to form a zygote, which is the first cell of the new organism. The zygote contains the full complement of chromosomes that will determine the characteristics of the organism. If the number of chromosomes in the sperm and egg were not equal, the zygote would not be viable and the organism would not develop properly.

As seen in the venn diagram, meiosis is responsible for the production of haploid gametes. Somatic or body cells are 2n cells. This change in chromosome number is the result of.

Answers

The change in chromosome number from diploid (2n) to haploid (n) during gamete formation is the result of two consecutive cell divisions, known as meiosis I and meiosis II.

Meiosis involves the replication of DNA followed by two rounds of cell division that result in the production of four genetically diverse haploid daughter cells. During meiosis I, homologous chromosomes pair and exchange genetic information through a process called crossing over. The homologous chromosomes then separate, leading to the formation of two haploid daughter cells.

During meiosis II, the sister chromatids of each chromosome separate, resulting in four haploid daughter cells with unique genetic combinations. This reduction in chromosome number is essential for sexual reproduction and ensures that the resulting offspring have the correct number of chromosomes.

In cats, black fur color is caused by an x-linked allele; the other allele at this locus causes orange color. The heterozygote is tortoiseshell. What kinds of offspring would you expect from the cross of a tortoiseshell female and an orange male?.

Answers

In cats, fur color is determined by an X-linked gene. Black fur is caused by a dominant X-linked allele, while orange fur is caused by the recessive allele. The heterozygous state for this gene results in tortoiseshell coloring.

Females have two X chromosomes, while males have one X and one Y chromosome. Therefore, a female tortoiseshell cat must have inherited one X chromosome with the black allele and another X chromosome with the orange allele.

If this tortoiseshell cat were to mate with an orange male cat, all of the female offspring would be tortoiseshell, inheriting one black X chromosome from the mother and one orange X chromosome from the father. All of the male offspring would inherit the orange X chromosome from the mother and the Y chromosome from the father, resulting in orange fur.

Therefore, all of the offspring would have orange fur, but the females would be tortoiseshell.

Answers

The brown scales are an advantageous trait because they provide a survival benefit to the fish by making them less visible to predators in their environment. This increased camouflage can result in better chances of survival and reproduction for fish with this trait.

In this scenario, the brown scales on some fish are an advantageous trait because they provide a selective advantage in the specific environment where they live. The brown scales make it harder for predators to see the fish, which can increase their chances of survival and reproduction.

The frequency of the brown scales in the population may increase over time as individuals with this trait are more likely to survive and reproduce. As a result, the advantageous trait becomes more common in the population, potentially leading to a shift in the predominant phenotype of the fish.

This process is an example of natural selection, a key mechanism of evolution.

In muscle cells, myosin molecules continue moving along actin molecules as long as.

Answers

In muscle cells, myosin molecules continue moving along actin molecules as long as (d) ATP is present and the intracellular Ca²⁺ concentration is high.

In muscle cells, myosin and actin filaments slide past each other during contraction, resulting in muscle shortening. This process is initiated by the release of calcium ions (Ca²⁺) from the sarcoplasmic reticulum, which binds to troponin and causes tropomyosin to move away from the myosin-binding sites on actin.

Once the binding sites are exposed, myosin heads bind to actin, forming cross-bridges. The hydrolysis of ATP provides the energy for the myosin heads to pull the actin filament, causing it to slide past the myosin filament. As long as ATP is present and the intracellular Ca²⁺  concentration is high, myosin continues to move along actin, resulting in sustained muscle contraction.

Will Give Brainliest!!

Answers

Answer:

Prenatal development.

Explanation:

Prenatal development is the period from conception until birth.

in Drosophila, two mutations, Stubble(Sb) and curled(cu), are linked on chromosome lll. Stubble is a dominant gene that is lethal in a homozygous state, abd curled is a recessive gene.
female: Sb cu / + +
male: + cu / + cu
if the cross is made, and if Sb and cu are 8.2 map units apart on chromosome lll, and is 1000 offspring were recovered,
a) how many ofspring would have stubble bristles and curled wings?
b) how many offspring would have stubble bristles and normal wing?
c) how manu offspring would have curled wings and normal bristles?

Answers

a) Based on the information given, we know that the female parent carries the dominant Stubble allele (Sb) and the recessive curled allele (cu), while the male parent carries two copies of the curled allele (cu/cu). This means that all of the offspring will inherit one copy of the curled allele from their father, but only half of them will inherit the Stubble allele from their mother. Therefore, the expected proportion of offspring with both traits is: 1/2 x 1/2 = 1/4.

To calculate the actual number of offspring with both traits, we need to use the total number of offspring and the proportion we just calculated. So, if 1000 offspring were recovered, then 1/4 of them (or 1000 x 1/4 = 250) would have stubble bristles and curled wings.

b) For offspring with stubble bristles and normal wings, we know that they must inherit one copy of the Stubble allele from their mother, but not the curled allele from their father. This means that they must inherit the wild-type allele (+) from their father, which is present in both copies. Therefore, the expected proportion of offspring with stubble bristles and normal wings is: 1/2 x 1/2 = 1/4.

Using the same method as before, we can calculate the actual number of offspring with these traits as: 1000 x 1/4 = 250.

c) Finally, for offspring with curled wings and normal bristles, we know that they must inherit two copies of the recessive curled allele (cu/cu), but not the dominant Stubble allele from their mother. This means that they must inherit the wild-type allele (+) from their mother, which is present in both copies. Therefore, the expected proportion of offspring with curled wings and normal bristles is: 1/2 x 1/2 = 1/4.

Using the same method as before, we can calculate the actual number of offspring with these traits as: 1000 x 1/4 = 250.
To determine the expected number of offspring with specific phenotypes, we can use the recombination frequency (map units) and the total number of offspring.

a) Stubble bristles (Sb) and curled wings (cu):
Since Sb and cu are 8.2 map units apart, the recombination frequency is 8.2%. Since we have 1000 offspring, the expected number of offspring with this phenotype is 8.2% of 1000, which is 82 offspring.

b) Stubble bristles (Sb) and normal wings (+):
This phenotype results from non-recombinant gametes. The probability of non-recombination is 100% - 8.2% = 91.8%. Since we have 1000 offspring, the expected number of offspring with this phenotype is 91.8% of 1000, which is 918 offspring.

c) Curled wings (cu) and normal bristles (+):
This phenotype results from recombinant gametes, and the expected number of offspring with this phenotype is the same as in (a) since Sb is lethal in the homozygous state, and no offspring will have the recessive normal bristle allele in this case. Therefore, 82 offspring would have curled wings and normal bristles.

Answers

In many signaling pathways, once a signaling molecule binds to a receptor, the receptor becomes phosphorylated. this initial phosphorylation step best demonstrates: receptor activation.

In many signaling pathways, the binding of a signaling molecule to its receptor initiates a cascade of events that ultimately leads to a cellular response. One of the earliest events in this cascade is the phosphorylation of the receptor. This initial phosphorylation step best demonstrates receptor activation, as it triggers a conformational change in the receptor that allows it to interact with downstream signaling proteins.

Receptor activation sets off a series of events known as signal transduction, which involves the propagation of the signal from the receptor to intracellular targets. This process involves the activation of various signaling pathways, such as protein kinase cascades, and ultimately leads to a cellular response.

Answers

The bowling ball would move farther than the soccer ball because it has more mass.

This is due to Newton's second law of motion, which states that force is equal to mass times acceleration (F=ma). If two objects are pushed with the same force, the object with greater mass will have less acceleration than the object with less mass.

Therefore, the soccer ball, which has less mass, will accelerate more than the bowling ball, but the bowling ball will travel farther due to its greater mass. This is also known as inertia, which is the tendency of an object to resist a change in its state of motion.

Why is 60 degrees north the earliest sunrise on june 21.

Answers

The combination of axial tilt, Earth's rotation, and the position of the Sun on June 21 leads to the earliest sunrise at 60 degrees north latitude.

Why is 60 degrees north the earliest sunrise on June 21?

On June 21, the Earth experiences the summer solstice in the Northern Hemisphere, which is the longest day of the year. At this time, the Earth's axial tilt is at its maximum towards the Sun. As a result, regions located around 60 degrees north latitude will experience their earliest sunrise.

The factors contributing to this are:
1. Axial tilt: The Earth's tilt of about 23.5 degrees causes variations in daylight hours during different seasons.
2. Earth's rotation: As the Earth rotates, different regions experience sunrise at different times.
3. Position of the Sun: On June 21, the Sun is directly over the Tropic of Cancer (23.5 degrees north latitude), leading to maximum daylight hours in the Northern Hemisphere.

So, the combination of axial tilt, Earth's rotation, and the position of the Sun on June 21 leads to the earliest sunrise at 60 degrees north latitude.

At approximately 1am last night, Philadelphia police were dispatched to the Old City section of our town. It was discovered at that time that The National Monument, The Liberty Bell, a symbol of this great countries history and freedom, was not in the location where it has been sitting in glory for hundreds of years. The Liberty Bell has been sitting at the Liberty Bell Center in the Independence National Historic Park since the year 1752. As of about Midnight, it is no longer in place. It was automatically assessed by the police that a burglary had taken place and several of our nation's top-level detectives and investigators were called in. ForThePeople News stood by with them as they started to assess the crime scene and to try to acquire witnesses To help them address the crime that they were confronting. The police were able to locate a reliable witness who has claimed to have seen some sketchy activity in the area, not too long before the crime was reported. Ms. Bertha Brown of Kensington claims that at approximately twelve-forty-five last night, she saw a white van with several muscular built Hispanic men as passengers, loading a mysterious and bulky object into the white van and pulling of at a ferocious speed. Ms. Brown states that she was walking her Yorkshire terrier at that point in time which is why she was even out that late at night. She initially thought that the activity of these men was suspicious, and when she saw the police arrive, she understood the very serious nature of the situation that was at hand and that she had witnessed. After speaking with Ms. Brown at length at their police precinct, the detectives set out to find the culprits who have committed this hateful crime against the American people. An APB was put out within all of the law enforcement communities and all of the news outlets were notified to broadcast the situation, and to stress the description of the burglars that was provided to the police by Ms. Bertha Brown. Currently the police are on high alert for any Hispanic men in white vans. At this point in time the Liberty Bell has not been relocated. Here at ForThePeopleNews.com, we are praying for the safe return of the Liberty Bell. This Bell is a symbol of Freedom, Pride, and National History for the American people and we want our Liberty Bell back! True False 1. 2x+8+9x^2+89/2322.
