Transferable Plasmids Useــــــــــــــــ as a Form of Replication During Transfer

Question

Transferable plasmids useــــــــــــــــ as a form of replication during transfer.
A)bidirectional replication
B)rolling circle replication
C)conservative
D)none of the above

Accepted Answer

Transferable plasmids use rolling circle replication as a form of replication during transfer. Rolling circle replication involves the unidirectional unwinding of DNA and the synthesis of new DNA strands using the original strand as a template. This results in a long single-stranded DNA molecule that can be transferred to another host cell.
