Question

The alphabets ‘B’ and ‘R’ in the plasmid pBR322 represent which of the following?

• A. Names of the scientists who developed the plasmid
• B. Name of the restriction endonuclease enzymes
• C. Name of University where vector was developed
• D. Strain of bacteria

Answer 1

The correct option is A Names of the scientists who developed the plasmid

The DNA molecule pBR322 was one of the first artificial cloning vectors (plasmid) constructed by Bolivar and Rodriguez.

Here, p stands for Plasmid, B for Bolivar, R for Rodriguez and 322 is the number given to this plasmid to distinguish it from other vectors they developed in their laboratory.
