NEET 2008 Biology question

The linking of antibiotic resistance gene with the plasmid vector became possible with

(1)Exonucleases
(2)DNA ligaseCorrect
(3)Endonucleases
(4)DNA polymerase

Answer: (2)

Solution

Restriction endonucleases cut the plasmid and the foreign DNA (here, the antibiotic resistance gene) at specific sites producing sticky ends; DNA ligase then joins the gene to the plasmid vector by forming
