Question

Restriction enzymes are referred to as 'molecular scissors' because they:

Options

• Synthesize new DNA molecules

• Denature and separate DNA strands

• Cut DNA at specific locations

• Ligate DNA fragments together

Answer 1

Restriction enzymes are called molecular scissors because they cut DNA at specific locations. These enzymes recognize specific DNA sequences and make precise cuts, allowing scientists to isolate and manipulate specific genes for use in recombinant DNA construction.
