Correct Answer

A. methylation ने enzyme cutting रोक दी हो सकती हैMethylation may have blocked enzyme cutting

Step 1

Concept

Some enzymes cannot cut methylated sites. Therefore the expected restriction cut may not appear.

Step 2

Why this answer is correct

The correct answer is A. methylation ने enzyme cutting रोक दी हो सकती है / Methylation may have blocked enzyme cutting. Some enzymes cannot cut methylated sites. Therefore the expected restriction cut may not appear.

Step 3

Exam Tip

कुछ enzymes methylated sites को काट नहीं पाते। इसलिए expected restriction cut नहीं दिख सकता।
