Question

In pBR 322, the gene sequence that codes for the proteins involved in replication of the plasmid is

• A. Pvu II
• B. Cla I
• C. rop
• D. pst I

Answer 1

Answer: (C)

rop

The rop gene in pBR322 codes rop protein, which is involved in stabilizing the interaction between RNA I and RNA II, which in turn prevents the replication of pBR322.

So the correct answer is C.
