Question: 117. 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
Answer: Option (2)
Explanation:
Hind II is a restriction endonuclease enzyme that recognizes a specific sequence of base pairs in DNA.
The recognition sequence of Hind II is a palindromic DNA sequence, meaning it reads the same in the 5′ to 3′ direction on both strands.
This recognition sequence is composed of 6 base pairs, which is characteristic of many restriction endonucleases used in genetic engineering.
Hind II cuts the DNA at a specific site within this 6 base pair recognition sequence, producing defined DNA fragments.
Therefore, the recognition sequence of Hind II consists of 6 bp.
