During specialized transduction carried out by lambda phage in Escherichia coli,differences in the phage and host attachment (att)sites mediate insertion of phage DNA into host DNA.

Question

Quizplus · Accepted Answer

During specialized transduction carried out by lambda phage in Escherichia coli, the phage and host attachment (att) sites are specific sequences where recombination occurs, allowing the integration of phage DNA into the host DNA. The process does not rely on differences between the att sites but rather on their specific sequences and the action of site-specific recombinases that mediate the recombination event.
