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.

Answers

DNA is a molecule that controls cellular activity by directing the synthesis of proteins.

Where DNA is present?

The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs.

Thus, DNA is a molecule that controls cellular activity by directing the synthesis of proteins.

While a home was undergoing a renovation, workers discovered that there was asbestos in the walls. Before any further work could be attempted, the family that owned the house had to evacuate, and specialists were brought in to remove the asbestos. Why would the house contain a substance that forced the family to be evacuated? Asbestos is not harmful, and the family was evacuated due to routine construction protocol.
Asbestos was once thought to be very useful, but now it is linked to lung cancer so the family was evacuated.
Asbestos is not harmful, but the family was evacuated so that the asbestos could be recycled for another building.
Asbestos was thought to be useful and is no longer used due to increasing costs to manufacture it.

Answers

B.
Asbestos was used in housing for many years because it was cheap to manufacture and was amazingly heat-resistant, but was found to be incredibly dangerous, causing innumerous accounts of lung cancer and related problems.
