**Reverse transcription** (RNA → DNA) is a hallmark of:
ABacteria
BRetroviruses (e.g. HIV)
CEukaryotic somatic cells
DBacteriophages
Answer & Solution
Correct answer: B. Retroviruses (e.g. HIV)
Retroviruses (HIV, etc.) carry RNA genomes and use reverse transcriptase (RNA-dependent DNA polymerase) to synthesise DNA from RNA — discovered by Temin and Baltimore (1970), modifying the central dogma.
