Question

In recombinant DNA technology, which enzyme is used to cut DNA at specific recognition sites to produce restriction fragments?

• A. DNA polymerase
• B. Restriction endonuclease
• C. Ligase
• D. Reverse transcriptase

Hint:

In recombinant DNA technology, remember that restriction endonucleases cut DNA at specific sites, ligase joins DNA fragments, and DNA polymerase amplifies DNA. Each enzyme has a distinct role in genetic engineering.
