Enzymes Role in Genetic Engineering A. Restriction Enzyme 1. Cuts DNA at specific sites B. DNA Polymerase 2. Synthesizes new DNA strands C. DNA Ligase 3. Unwinds DNA strands D. Helicase 4. Joins DNA fragments

Options

  1. AA - 2, B - 1, C - 4, D - 3
  2. BA - 1, B - 2, C - 4, D - 3
  3. CA - 3, B - 4, C - 2, D - 1
  4. DA - 4, B - 3, C - 1, D - 2

Correct answer

B. A - 1, B - 2, C - 4, D - 3

Step-by-step solution

Restriction enzymes cut DNA at specific sites, DNA polymerase synthesizes new DNA strands, DNA ligase joins DNA fragments, and helicase unwinds DNA strands.
