How are restriction endonucleases used in genetic engineering?

Options

  1. ATo remove nucleotides from the ends of the DNA
  2. BTo form recombinant molecules of DNA
  3. CTo separate the fragments of DNA
  4. DTo cut the strand of DNA

Correct answer

D. To cut the strand of DNA

Step-by-step solution

Restriction enzymes belong to a larger class of enzymes called nucleases. These are of two kinds; exonucleases and endonucleases. Exonucleases remove nucleotides from the ends of the DNA whereas, endonucleases make cuts at specific positions within the DNA. >.
