Question

Restriction Endonuclease – Hind II always cuts DNA molecules at a particular point by recognising a specific sequence of:

• A. Six base pairs
• B. Four base pairs
• C. Seven base pairs
• D. Three base pairs

Hint:

Most restriction enzymes recognize palindromic sequences of 4–8 base pairs; Hind II specifically recognizes 6 bp.

Answer 1

The Correct Option is A

Restriction endonucleases are enzymes that cut DNA at specific recognition sites.
Hind II was the first restriction enzyme discovered that cuts DNA at a specific recognition sequence.
It recognizes a sequence of exactly six base pairs and cuts DNA at that site.
Hence, the correct answer is six base pairs.
