A scientist uses radioactive nitrogen to label the nitrogenous bases of the DNA of a cell. Then the DNA is allowed to replicate, and the new strands take up non-radioactive bases. Do one, both, or neither of the daughter cells have radioactive DNA? Explain.

Answers

Answer 1

I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.

Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.

Sorry if im wrong

Answer 2

Answer:

I would say one..

Explanation:

It says the new strands take u non-radioactive bases.. if he only used the radioactive to label one of them then I would say one..

Merle is a marking pattern in canine coats that appears as a marbling of color in a solid coat. The merle gene displays incomplete dominance.
CSCS individuals display a solid coat
CMCS individuals are merle and show patches of fur with a lighter, mottled effect
CMCM individuals are "double merle" and show patches of fur with much more pronounced lightening
Another gene, FGF5, also influences coat phenotype and determines whether dogs display long or short coats, with short coats being dominant to long coats.

Answers

Answer:

The correct answer is - reuptake.

Explanation:

The process that reabsorbs the neurotransmitters known as reuptake which reduced the number of neurotransmitter molecules. Neurotransmitter transporter found on the outer membrane of the plasma membrane assists the process of reuptake by reabsorbing the neurotransmitter molecules from the specific synaptic gap. Neurotransmitters recycle by this process in order to reuse again after a time for the particular signal to last.

Thus, the correct answer is - reuptake.

a. Mitochondria has its own DNA
b. Mitochondria have their own nucleus
c. Mitochondria has it's own membrane
d. Mitochondria has its own ribosomes ​

Answers

Answer:

The correct answer is - option B. mitochondria have their own nucleus.

Explanation:

Endosymbiotic theory is a evolutionary theory which explains how eukaryotic cells evolved from prokaryotic organisms.

Evidences of endosymbiotic theory are:

1. Mitochondria and chloroplasts are double membrane bound cell organelles. The inner membrane probably evolved from the plasma membrane of engulfed bacterium and outer membrane from the plasma membrane or endoplasmic reticulum of the host cell.

2. Almost similar size of mitochondria and chloroplast and bacteria and their ribosomes.

3. Cristae of mitochondria resemble the folded membranes is groups of bacteria.

4. Mitochondrion and chloroplast both have circular DNA similar to those of bacterial DNA.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?

Answers

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

Explain the difference between sex hormones and glandular stimulating hormones

Answers

Answer:

Sex hormones are those hormones that within the endocrine system of the human being, are considered more directly involved in human sexuality, particularly in the processes of copulation and reproduction.On the other hand, glandular stimulating hormones are those that act on hormonal production in another endocrine gland, that is, they are stimulants, since they stimulate the corresponding glands.

Explanation:

Sex hormones are chemical substances secreted by the sex endocrine glands (the testes and ovaries) and subsequently released into the bloodstream, to be transported to the organs on which they exert their action (increasing or decreasing their activity).The production of hormones is regulated in many cases by a negative feedback system, which causes an excess of a hormone to be followed by a decrease in its production. The glandular stimulating hormones are transported to the blood to stimulate the corresponding glands (thyroid, adrenal cortex, and gonads) and these will be the ones that secrete various types of hormones (thyroxine, corticosteroids and sex hormones, respectively), which in addition to acting in the body, they feed back into the pituitary and hypothalamus to inhibit their activity and balance the respective secretions of these two organs and the target gland. For example, follicle-stimulating hormone encourages sperm production in men and stimulates the ovaries to release eggs in women. Luteinizing hormone and follicle stimulator work together to allow normal function of the ovaries or testicles.

Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle?

Answers

Answer: Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle? ... Since not all organisms can utilize the nitrogen gas directly, these microorganisms convert nitrogen in different nitrogen compounds, such as ammonia, nitrites, and nitrates. In this article we explore how nitrogen is cycled and the important role of microbes in this cycle. ... Nitrogen is required by all living organisms for the synthesis of organic molecules such as amino acids, nucleic acids and proteins. The Earth's atmosphere contains almost 80% nitrogen gas

Bacteria play a central role:

Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.

Bacteria of decay, which convert decaying nitrogen waste to ammonia.

Nitrifying bacteria, which convert ammonia to nitrates/nitrites.

Denitrifying bacteria, which convert nitrates to nitrogen gas.

In some bunnies, the gene for fur color is controlled by condominance. The allele for gray color is G and the allele white color is W. The heterozygous phenotype results in a gray and white bunny/ What is the genotype for gray bunnies? what is the genotype for white bunnies? what is the genotype for gray and white bunnies?

Answers

Answer:

Genotype gray bunnies: GG

Genotype white bunnies: WW

Genotype gray and white bunnies: GW

Explanation:

In diploid species (2n), organisms receive one gene copy (allele) from each parent. Codominance is a relationship that occurs when both alleles of the same gene show dominance. In consequence, the expression of both alleles in heterozygous individuals results in a new phenotype. In this example, the expression of G and W alleles results in a gray and white phenotype. Examples of codominance include individuals with type AB blood group in humans or the roan coat color in horses.
