Sticky ends are produced when restriction enzymes cut fragments of DNA.The advantage of these sticky ends in recombinant DNA technology is to :
Correct answer: D. Facilitate the insertion of foreign DNA into vector
- A. Isolate the gene of interest
- B. Identify the plasmids in bacteria
- C. Synthesise the complementary DNA from mRNA
- D. Facilitate the insertion of foreign DNA into vector
Explanation
Sticky ends have short single-stranded overhangs that can form complementary base pairs with matching ends on another DNA fragment. This makes it much easier and more accurate to insert foreign DNA into a plasmid/vector.So D is the correct option. Rest of the options are incorrect.
