Question

In the E.coli chromosome the origin of replication,called oriC,is characterized as being rich in:
A) A-T base pairs
B) A-G base pairs
C) C-G base pairs
D) C-T base pairs
E) G-T base pairs

Accepted Answer

The origin of replication in E.coli chromosome, oriC, is characterized by a high AT content (around 70%) which makes it easier to denature the DNA double helix and initiate replication. This high AT content enables the DNA to melt easily and thus facilitates the binding of the replication initiation proteins.
