Question

While cloning vectors, which of the two will be performed by biotechnologists bacteriophages or plasmids. Justify with reason.

Answer 1

Plasmids used as vectors maintain a modified origin of replication that allows their replication within the host, and they contain a gene for antibiotic resistance which ensures that, following treatment with a high dose of antibiotic, all viable bacterial colonies will contain several copies of the plasmid.
