In the E. coli cloning vector pBR322, the role of 'ori' and 'rop' gene are:
- A'ori' is responsible for controlling the copy number of the linked DNA, and 'rop' for the protein involved in the replication of plasmid.
- B'ori' is for the protein involved in the replication of plasmid, and 'rop' for resistance to antibiotics.
- C'ori' is responsible for recognition sites, and 'rop' is responsible for antibiotic resistance.
- D'ori' is responsible for resistance to antibiotics, and 'rop' for the protein involved in the replication of plasmid.
Solution & Step-by-step Explanation
ori (Origin of replication): The sequence where replication starts; it also controls the copy number of the linked DNA.rop: Codes for the proteins involved in the replication of the plasmid.
