Question

Genetic material of retrovirus is

• A. ss RNA
• B. ss DNA
• C. ds RNA
• D. ds DNA

Answer 1

The correct option is A ss RNA

A retrovirus is a single-stranded positive-sense RNA virus with a DNA intermediate which causes tumors and cancers.

This virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome and the new DNA is then incorporated into the host cell genome.

The host cell then treats the viral DNA as part of its own genome, transcribing and translating the viral genes along with the cell's own genes and produces the proteins required to assemble new copies of the virus.

So, the correct answer is 'ss RNA'.
