Question

How many fragments will be generated if you digest a linear DNA molecule with a restriction enzyme having four recognition sites on the DNA?

• A. 3
• B. 6
• C. 5
• D. 4

Answer 1

Answer: (C)

5

If DNA is linear then the number of fragments generated is (N+1), where N= number of recognition sites or sequences.

Hence the number of fragments generated is 5 if we digest a linear DNA molecule with a restriction enzyme having four recognition sites on the DNA.

So, the correct option is 'Option C'.
