Question

not sure that the highlighted answer is right

36. The lambda genome is replicated by a rolling circle mechanism. What is the end result after replication? donde a. a single-stranded DNA that is immediately packaged in the phage head! b. two molecules resulting from a step of circle-to-circle replication C. several circular molecules inserted into each other, the circles are cleaved at the cos sites and eventually relegated d. a concatemer Lecture 1 Chill Shield 14 e. several Okazaki fragments that are subsequently ligated

Answer 1

In rolling circle mechanism, concatemeric DNA molecules (contains multiple copies of the genome) are synthesized from a circular template in which nicking of one strand allows the other strand to be copied repeatedly multiple times.
