Question

Hind II always cuts DNA molecules at a particular point called recognition sequence and it consists of:
(1) 8 bp
(2) 6 bp
(3) 4 bp
(4) 10 bp

Accepted Answer

Correct Answer: B — 6 bpStep-by-step Solution:Hind II is a type II restriction endonuclease isolated from Haemophilus influenzae. It recognizes a specific palindromic DNA sequence and cuts within it. The recognition sequence for Hind II is 5'-GTPyPuAC-3' (where Py = pyrimidine, Pu = purine), which is a 6-base pair sequence. Typically, most type II restriction enzymes recognize 4, 6, or 8 bp sequences. Hind II is known to recognize a 6 bp sequence. Hence, the correct answer is 6 bp.Key Concepts: Restriction enzymes (endonucleases), recognition sequences, palindromic sequences, Hind II, type II restriction enzymes.
