Question

In DNA recombination, what is created when the DNA is opened up at the restriction site?

Responses

A double-stranded DNAdouble-stranded DNA

B RNARNA

C sticky ends

Answer 1

C. Sticky ends.

Step-by-step explanation:

C. Sticky ends.

When the DNA is opened up at the restriction site during DNA recombination, the enzyme creates a double-stranded cut leaving short, single-stranded overhangs called sticky ends. These sticky ends can base pair with complementary sticky ends generated by the same restriction enzyme on another DNA molecule, allowing the two DNA molecules to be joined together. This process is used in DNA cloning and other genetic engineering techniques.
