Question

I'll just the question straight up,

"In E. Coli, which terms accurately reflect the nature ofreplication of the chromosome?

I have four choices, but two of them are "unidirectional" andI know E. Coli replication is BIdirectional. So the other optionsare:

a) bidirectional and multirepliconic
b) bidirectional and fixed point of initiation

I know it starts at a replication fork, but, "fixed point"...doesthat mean it starts at just one point? I'm not sure whatmultirepliconic means anyway.

Sorry if this is a stupid question : (

Explanation / Answer

The   answer   is ( B)   bidirectionaland fixed point of initiation     as   the   bacterial genome is   circular with   a  single    origin site   Ori C   where the   replication starts .But as   both   the  strands   are    undergoing  replication therefore   it  is   bidirectional .
