Explain the importance of (a) ori, (b) `amp^(R)` and (c) rop in the E. coli vector shown below .

Explanation

a = ori = origin of replication
b = `amp^(R)` = ampicillin resistance genes
c = rop = Proteins involved in replication of plasmid
ori = origin of replication is a specific portion of plasmid genome that serves as start signal for self replication .
Plasmids are characterised to possess some important genes like the antibiotic resistance gene like `amp^(R), tet^(R)`
The proteins produced by rop genes will help in the replication of plas-
