Question

Ribovirus is a group of virus which contains

• A. Double stranded DNA
• B. Single stranded DNA
• C. RNA
• D. None of the above

Answer 1

Answer: (C)

RNA

Ribovirus is a group of virus which contains RNA as its genetic material. It do not include DNA intermediates in their replication cycle. The RNA can be double-stranded or single-stranded. It has RNA as its genome which is inserted into the host. On insertion, the RNA is converted to mRNA by RNA polymerase which is further translated into viral protein. Some of the RNA is used to synthesize the complementary strand by the enzyme replicate.

So, the correct answer is option C.
