Question

Identify the plasmid from the following.

• A. AIU I
• B. Hind III
• C. Eco RI
• D. pBr 322.

Answer 1

The correct option is D pBr 322.

pBR322 is one of the common plasmid vectors. The size of this vector is 4361 bp. There is an ori site which is the site for replication. There are multiple recognition and cloning sites which are used for the insertion of genes. There are antibiotic resistance genes like ampicillin ($am{p}^R$) and tetracycline ($te{t}^R$).

Thus, the correct answer is option D.
