Question

During generalized transduction, which of the following is true?

1) The host chromosome is degraded into randomly sized fragments.
2) Any DNA fragment of the appropriate size is packaged.
3) Any bacterial gene may be transferred to the subsequent host.
4) All of the choices are correct.

Answer 1

During generalized transduction, any piece of chromosomal DNA may be transferred by accidental packaging of the degraded host chromosome into a phage head. This process occurs during the lytic cycle of viral replication. Bacterial genes can be transferred to the subsequent host, leading to DNA recombination.

Step-by-step explanation:

During generalized transduction, any piece of chromosomal DNA may be transferred by accidental packaging of the degraded host chromosome into a phage head. This process occurs during the lytic cycle of viral replication when the virus assembles and packages DNA into the phage head. Instead of packaging viral DNA, the phage occasionally takes a random piece of host DNA and inserts it into the capsid. This results in the transfer of bacterial genes to the subsequent host, allowing for DNA recombination to occur.
