What would be observed in a cell infected with a T7 phage mutated in gene 3 (endonuclease gene).

Question

Quizplus · Accepted Answer

Gene 3 of T7 phage encodes an endonuclease necessary for the resolution of concatemeric DNA into genome-length units for packaging into new phage particles. A mutation in this gene would lead to the accumulation of concatemers of the viral genome, as the DNA would not be properly cleaved into individual genomes.
