Which of the following accurately describes the role of DNA ligase in genetic engineering?

  • A: Seals the base-paired fragments to produce recombinant DNA molecules.
  • B: Cuts DNA molecules at specific nucleotide sequences.
  • C: Amplifies a specific target segment of DNA.
  • D: Separates DNA fragments of different lengths.

Explanation

The text states that 'Sealing the base-paired fragments with DNA ligase produces recombinant DNA molecules,' directly defining its role in joining DNA fragments.
