The Molecules Used to Cut Target DNA in Genetic Engineering

Question

The molecules used to cut target DNA in genetic engineering are
A) exonucleases.
B) restriction enzymes.
C) proteases.
D) RNA polymerases.
E) DNA ligases.

Accepted Answer

Restriction enzymes are used to cut target DNA in genetic engineering. These enzymes recognize specific nucleotide sequences in DNA and cleave the DNA molecules at those sites. This allows for the manipulation and modification of DNA sequences for various genetic engineering applications.
