You are a virologist interested in studying the evolution of viral genomes. You are studying two newly isolated viral strains and have sequenced their genomes. You find that the genome of strain 1 contains 25% A, 55% G, 20% C, and 10% T. You report that you have isolated a virus with a single-stranded DNA genome. Based on what evidence can you make this conclusion

Answers

Answer:

See the answer below

Explanation:

In double-stranded DNA, the ratio of purine bases (Adenine and Guanine) and that of pyrimidine bases (Thymine and Cytosine) is 1:1 according to Chargaff's rule. This means that the percentage of Adenine must be equal to that of Guanine while that of Thymine must also be equal to Cytosine.

However, in the case of the newly isolated viral strain, the amount of Adenine (25%) and Guanine (55%) vary while that of Thymine (10%) and Cytosine (20%) also vary. This is in contrast to Chargaff's rule. Hence, the isolated virus is a single-stranded DNA virus instead of a double-stranded.

Jenna says that an example of homeostasis is when body temperature is maintained at about 37° C. Allen says homeostasis is when breathing rate increases along with exercise. Who is correct? A. Only Allen is correct. B. Both are correct. C. Only Jenna is correct. D. Neither is correct.

Answers

B. Both are correct

Both are correct is the accurate answer. Why? Because as Jenny said our body maintains our temperature at approximately 37C which is the conditional temperature where our cells could do significant and existential processes. Also is maintained by the hypothalamus. Moreover, when we exercise, the amount of oxygen decreases thus muscles around the thoracic region increase the breathing rate.
