Question

What evidence supports these exceptions?

a. The bacteriophage T2 is composed of an RNA core and a protein coat.
b. The tobacco mosaic virus is composed of an RNA core and a protein coat.
c. Retroviruses contain RNA as the genetic material and use an enzyme reverse transcriptase to produce DNA.
d. Smallpox virus contains RNA as the genetic material and uses an enzyme reverse transcriptase to produce DNA.

Answer 1

The evidence supporting these exceptions includes scientific studies and observations of their structures, as well as experiments and research in virology.

Step-by-step explanation:

There is evidence to support these exceptions:

1. The bacteriophage T2: The fact that the bacteriophage T2 is composed of an RNA core and a protein coat is supported by scientific studies and observations of its structure.
2. The tobacco mosaic virus: The presence of an RNA core and a protein coat in the tobacco mosaic virus has been confirmed through experiments and research in virology.
3. Retroviruses: Scientific evidence supports the fact that retroviruses contain RNA as their genetic material and use the enzyme reverse transcriptase to produce DNA. This has been extensively studied and documented.
4. The smallpox virus: Scientific research has shown that the smallpox virus contains RNA as its genetic material and uses the enzyme reverse transcriptase to produce DNA. This information has been verified through various studies.
