Biology Question 112 – NEET-UG 2024
Hind II always cuts DNA molecules at a particular point called recognition sequence and it consists of:
🧠 Full Solution Path
Step 1: Identify the enzyme and its function✦ Active
Hind II is a restriction endonuclease, which is an enzyme that cuts DNA molecules at specific recognition sequences. These enzymes are crucial tools in genetic engineering.
Step 2: Recall the characteristics of Hind II○ Expand
Hind II was the first restriction endonuclease discovered and characterized. It is known to recognize a specific palindromic nucleotide sequence in DNA.
💡 Teacher's Secret Hint
Remember that different restriction enzymes recognize different lengths and sequences of DNA.
Step 3: Determine the length of the recognition sequence○ Expand
The specific recognition sequence for Hind II consists of 6 base pairs (bp).
💡 Teacher's Secret Hint
This is a factual recall question. Knowing the specific characteristics of common restriction enzymes like Hind II is important.
