Phage DNA that has been incorporated into a bacterial genome carries which name?
AA prophage
BA capsomere
CA replicon
DA virion
Answer & Solution
Correct answer: A. A prophage
1. A temperate bacteriophage can replicate by the lysogenic cycle.
2. In that cycle the viral genome is incorporated into the genome of the host cell.
3. Phage DNA that sits inside the host genome in this way is called a prophage.
4. A virion is a free virus particle and a capsomere is a capsid subunit, so neither term fits integrated DNA.
