Question

Rolling circle mode of replication is ________

(a) Conservative

(b) Non Conservative

(c) Semi – Conservative

(d) Dispersed

I had been asked this question during an interview.

My query is from DNA Replication Prokaryotes topic in chapter DNA Replication of Cytogenetics

Answer 1

Correct answer is (c) Semi – Conservative

To explain: One cycle of replication results in an inner parent circular strand and outer daughter circular strand making the process semi-conservative. It would have been conservative if resultant parent and daughter strand would be on different molecules and dispersed if both strands would have some part of parent and daughter.
