QUESTION
Enzyme useful in genetic engineering is?
OPTIONS
(A) Lipase
(B) DNAse
(C) Restriction endonuclease
(D) Amylase
ANSWER
(C) Restriction endonuclease
EXPLANATION
Restriction endonucleases are essential tools of genetic engineering because they recognize specific DNA sequences and cleave DNA at or near those sites, allowing controlled manipulation and joining of DNA fragments. Lipase and amylase are digestive or metabolic enzymes, while DNase generally degrades DNA rather than providing the specific sequence-directed cutting used in recombinant DNA technology.
