Question

The detection of reverse transcriptase activity in a culture infected with a virion suggests the presence of

• A. The presence of a double-stranded DNA virus
• B. The presence of a single-stranded DNA virus
• C. The presence of a double-stranded RNA virus
• D. The presence of a single-stranded RNA virus

Answer 1

The correct option is D The presence of a single-stranded RNA virus

Retroviruses operate a central dogma reverse. RNA of these viruses first synthesis DNA through reverse transcriptase or RNA dependent DNA polymerase. This DNA synthesised on RNA template is called c-DNA or retroposons.

RNA------> c-DNA--------> RNA----> Protein

So, the correct option is 'The presence of a single-stranded RNA virus'
