Answer: Taq polymerase.
- A Taq polymerase
- B the DNA ligase used
- C only a restriction
- D a helicase enzyme
Correct answer: A. Taq polymerase
Explanation: Thermostable Taq polymerase extends primers in PCR.
Recombinant DNA technology: a gene of interest and plasmid are cut by the same restriction enzyme, ligated into a recombinant plasmid, and introduced into a host cell.
Concept context
