A scientist injects a drug called rifampicin, which inhibits RNA synthesis, into a bacterium. What is the most likely direct result of this alteration?

The bacterial DNA will stop replicating.
The bacterial DNA will replicate in an uncontrolled way.
The process of protein synthesis will stop in the bacterium.

Answers

Answer 1

The most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

What is Rifampicin drug used for?

The drug Rifampin is used to treat tuberculosis (TB) in many different parts of the body. It is also used by patients who have meningitis bacteria in their nose or throat who do not show symptoms of the infection to prevent the spread of the bacteria to other patients.

Rifampin specifically inhibits bacterial RNA polymerase. It is an enzyme that is responsible for DNA transcription, by forming a stable drug-enzyme complex with a binding constant of 10(-9) M at 37 C. The corresponding mammalian enzymes are not affected by rifampin.

Therefore, the most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

What is the biggest error, methodologically, in the following scientific study? "The goal of the study was to determine whether the ebola virus is as deadly in rhesus monkeys as it is in gorillas. I took a sample of four healthy rhesus monkeys and four healthy gorillas. The animals were a random mixture of sexes and ages. I arranged eight cages so that each animal would be in a separate cage, and I made sure there would be no contact among the cages that would allow transmission of the virus. Then I obtained a sample of the ebola virus from the National Institute of Infectious Diseases and injected all the monkeys and gorillas with the same size dose. At the end of four days, I noticed that all the gorillas were dead but only one of the monkeys was dead. An autopsy revealed that three of the four gorillas had died of ebola fever but that the fourth, nicknamed Curious George, had died of internal bleeding after swallowing the small pair of scissors that were left within reach of its cage. The dead monkey had died of ebola fever. At the end of two months there were no more deaths. I concluded that my dosage of the ebola virus is three times as likely to be deadly to gorillas as it is to rhesus monkeys, but I recommended repeating the study to see if the percentages of deaths due to ebola fever remained steady over a wide range of dosages of the virus."

Answers

Answer:

The sample obtained for the study is not enough. Also, a control group is not established thus making the study erroneous.

Explanation:

The total sample size of 4 specimens from each of the two groups does not qualify as an appropriate sample size for the generalization of the results. Furthermore, the mixing of different ages and genders is not suitable for this kind of sample.

Also, the control group is not established where healthy specimens are kept in a similar environment to factor out the effects of the environment and other components on the health/death of the animals.

if two chromosome have equal length and size , and different in gene number would severity of chromosomal abnormalities in this two chromosome are equal?​

Answers

Answer:

Unequal.

Explanation:

The severity of chromosomal abnormalities in these two chromosome are unequal that are equal in length and size but unequal in gene number are because the gene number are different from one another. If the size of gene increase or decrease from the normal range then it will leads to chromosomal abnormalities in the cell so the cells that has normal gene number has normal chromosome as compared to those cells where abnormal gene is present so the chromosomes are abnormal.

Jaguars are a keystone species in the Amazon. Describe how they can be so essential to the ecosystem despite
being significantly less abundant than many other species.

Answers

Answer:

jaguars are keystone species because they feed herbivorous species that might decimate the plants of the ecosystem

Explanation:

Keynote species are species that help to maintain the homeostasis of the ecosystem so if they lack then the ecosystem would change drastically. Moreover, a top predator is a predator that occupies the highest trophic level in the food chain. Jaguars are both keystone species and top predators that feed herbivorous species, maintaining the health of the food chain by eliminating the excess of primary consumers that otherwise would feed too many plants (i.e., primary producers) which produce and store energy at the bottom of the food chain.

What is the genetic make-up of an organism?

Answers

Answer:

Explanation:

In a broad sense,genetic makeup of an organism can be regarded as the

"genotype" . It gives description about

complete set of genes an organism.

If we narrow it, it can be reffered to as "alleles" , this is is variant forms of a gene which is been carried by an organism. For instance, Humans can be regarded as diploid organisms, i.e there are two alleles at their each genetic position along with one allele which is been inherited from each parent. genotype of a specific gene is been represented by "Each pair of alleles". Instance of this is of "sweet pea plants" the gene responsible for flowering color posses two alleles, One of the alleles is responsible for coding purple flowers, symbolized with

uppercase letter F, the other allele is responsible for coding of white flowers

symbolized with Lowercase letter" f "

There are three possible genotypes which could be featured for Different population of a sweet pea, which are

✓FF

✓Ff

✓ ff.

Genotype of each plant have some contribution to the phenotype, by saying this, we mean outward appearance of its flowers.

Answers

Answer: a frame shift mutation

Explanation:

ACGGGCAAACGATTG  to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines. as there is a deletion of a single base, ,so it is called a deletion mutation.

What is mutation?

This change can have various effects on the resulting protein, depending on the specific location of the mutation within the gene and the role of the affected amino acid in the protein's function. For instance, in a non-coding region of the gene, such a mutation might have no effect at all on the protein, as it would not affect the sequence of the mRNA that is transcribed from the gene. However, if the mutation occurs in a coding region of the gene, it can lead to a change in the resulting protein.

Hence, ACGGGCAAACGATTG  to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines.
