Question

What is the function of a restriction enzyme in recombinant technology?

Options

• Cut DNA into many fragments

• Link together newly joined fragments of DNA

• Make millions of copies of a specific segment of DNA

• Separate fragments of DNA by their length and electrical charges

Answer 1

Cut DNA into many fragments

Explanation:

The function of a restriction enzyme in recombinant technology is to cut DNA molecules at specific sites. These enzymes act like molecular scissors or chemical scalpels, cleaving DNA at recognized sequences and generating DNA fragments containing identifiable genes. This precise cutting allows for isolation and manipulation of specific DNA segments, which is essential for creating recombinant DNA by joining these fragments with vectors.
