NEET BIOLOGY

Detailed explanation-1: -Phage DNA recombines with bacterial chromosome and becomes integrated into the chromosome as a prophage.

Detailed explanation-2: -Prophage is a segment of Viral DNA incorporated into the host DNA. This DNA replicates along with the host DNA. This is a form of replication in virus where for a certain period of time the host cell is kept intact. This kind of reproduction in virus is called lysogenic type of reproduction.

Detailed explanation-3: -A prophage is a bacteriophage genome which is inserted and integrated into the circular bacterial DNA chromosome. This is a latent form of a phage in which the viral genes are present in the bacterium without causing disruption of the bacterial cell.

Detailed explanation-4: -Prophages are integrated viral forms in bacterial genomes that have been found to contribute to interstrain genetic variability. Many virulence-associated genes are reported to be prophage encoded.

Detailed explanation-5: -DNA integration is a unique enzymatic process shared by all retroviruses and retrotransposons. During integration, double-stranded linear viral DNA is inserted into the host genome in a process catalyzed by the virus-encoded integrase (IN).
