Which of the following does not have direct role in genetic engineering?

Lipase

The correct answer is Option (3) → Lipase

Restriction enzymes are crucial in genetic engineering as they cut DNA at specific sites, allowing for the insertion of new genes.

Polymerase (specifically DNA polymerase) is involved in amplifying DNA sequences through techniques like PCR (Polymerase Chain Reaction).

Vectors are used to transfer genetic material into host cells.

Lipase, on the other hand, is an enzyme that breaks down fats and does not have a direct role in genetic engineering.
