- The 5'→3' exonuclease activity of intact DNA polymerase I can replace a segment of DNA (or RNA) paired to the template strand, in a process known as ____________________.
- What is the function of RNA primer during DNA replication? A: to provide a 3’ OH group for DNA polymerase B: to provide a 5’ OH group for DNA polymerase C: to provide a 3’ phosphate group for DNA polymerase D: to provide a 5’ phosphate group for DNA polymerase E: to provide a hydrogen bond for double strand of DNA .
- Enzymes participating in DNA replication include: (1) DNA polymerase III; (2) melting enzyme; (3) DNA polymerase I; (4) RNA polymerase (primerase); (5) DNA ligase . The order of action is: A: (2), (4), (1), (3), (5) B: (4), (3), (1), (2), (5) C: (2), (3), (4), (1), (5) D: (4), (2), (1), (5), (3) E: (4), (2), (1), (3), (5)
