Match the following enzymes with their functions.

Column-I	Column-II
(A)	Restriction endonuclease	(I)	Joins the DNA fragments
(B)	Restriction exonuclease	(II)	Extends primers on genomic DNA template
(C)	DNA ligase	(III)	Cuts DNA at specific position
(D)	Taq polymerase	(IV)	Removes nucleotides from the ends of DNA

Select the correct option

-(II), -(III), -(IV), -(II),

-(I), -(IV), -(III), -(IV),

-(IV), -(I), -(I), -(I),

-(III) -(II) -(II) -(III)

Verified by Experts

The correct answer is:

→ (III): Restriction endonuclease → Cuts DNA at specific positions.

→ (IV): Restriction exonuclease → Removes nucleotides from DNA ends.

→ (I): DNA ligase → Joins DNA fragments together.

→ (II): Taq polymerase → Extends primers during PCR.
