Question

A foreign DNA and plasmid cut by the same restriction endonuclease can be joined to form a recombinant plasmid using

Answer 1

Ligase -

These enzymes form phosphodiester bonds between adjacent nucleotides and covalently link two fragments of double-stranded DNA.

-

Ligase are enzymes that join two phosphodiester bonds thus, forming recombinant plasmid.
