Question

What are proteins that cut both source and vector DNA used to create recombinant DNA?

a) Ligases
b) Restriction enzymes
c) Polymerases
d) Helicases

Answer 1

Restriction enzymes are proteins that cut both source and vector DNA to create recombinant DNA.

Step-by-step explanation:

In recombinant DNA technology, proteins that cut both source and vector DNA are known as restriction enzymes. These enzymes recognize specific DNA sequences, usually palindromic, and cut the DNA at those sites.

Each restriction enzyme cuts DNA at a characteristic recognition site, generating DNA fragments that can be spliced into another DNA molecule to create recombinant DNA.

This process allows scientists to insert a specific gene or DNA fragment into a sequence of interest.
