Which of the following is a plasmid?
Open in App
Solution
The correct option is A pBR322
The plasmid is an extrachromosomal genetic element of DNA or RNA that is capable of replicating independently of the host chromosome, e.g. E.coli plasmid pBR322. BamH I, Sal I and Hind III are restriction enzymes. A restriction enzyme or restriction endonuclease is an enzyme that cleaves DNA into fragments at or near specific recognition sites within the molecule known as restriction sites.
