Replication of DNA by rolling circle mechanism give rise to a
A. Blunt end DNA
B. Theta structure
C. Single strand DNA with nick
D. Concatamer
Answer: Option D
Solution(By Examveda Team)
Replication of DNA by rolling circle mechanism gives rise to a Concatamer.A concatemer is a long continuous DNA molecule that contains multiple copies of the same DNA sequence linked in series. Concatemers are frequently the result of rolling circle replication, and may be seen in the late stage of bacterial infection by phages.
In rolling circle replication, a circular template of DNA is replicated as a long single-stranded DNA concatamer that spools off when a strand displacing polymerase traverses the circular template.
