Question

Correctly match the viruses listed in Column I with the nature of their corresponding genetic materials listed in Column II:

• A. P - i; Q - iv; R - iii; S - ii
• B. P - iv; Q - ii; R - i; S - iii
• C. P - i; Q - iii; R - ii; S - iv
• D. P - i; Q - iii; R - ii; S - iv

Hint:

Bacteriophages can have either single-stranded or double-stranded DNA, while viruses like coronaviruses and reoviruses typically have RNA as their genetic material. The specific type of RNA or DNA defines their replication and infection mechanisms.

Answer 1

The Correct Option is C

Let us match each virus with its corresponding genetic material:
- P. Bacteriophage lambda: This bacteriophage has dsDNA (double-stranded DNA) as its genetic material. Therefore, P - i is correct.
- Q. Bacteriophage M13: This bacteriophage has ssDNA (single-stranded DNA) as its genetic material. Therefore, Q - ii is correct.
- R. Coronavirus: This virus has ssRNA (single-stranded RNA) as its genetic material. Therefore, R - iii is correct.
- S. Reovirus: This virus has dsRNA (double-stranded RNA) as its genetic material. Therefore, S - iv is correct.
Thus, the correct matching is P - i, Q - iii, R - ii, S - iv. Therefore, the correct answer is (C).
