Question

Plaques produced by the temperate phage lambda on E. coli are turbid, since some bacteria remain viable within the plaque area. Plaques produced by the virulent phage T4 are usually clear. Which statement is the BEST explanation for this difference? O A. Lambda often carries a portion of the sex factor. O B. Recombination occurs more frequently between lambda genomes than T4 genomes C. T4 will not infect E. coli cells that are growing D. T4 carries a smaller DNA genome than lambda. E. Lambda can propogate via the lytic or lysogenic cycle

Explanation / Answer

The answer is option E. Lambda can propagate via the lytic or lysogenic cycle.

T4 lambda phage can undergoes only lytic cycle. So we got clear plaques. But in case of lambda phage we got turbid plaques that means it can undergoes lysogenic cycle also.
