Taq DNA polymerase had no 5 ′ → 3 ′ exonuclease activity.
举一反三
- DNA polymerase Ⅲ has a 5’→3’exonuclease activity
- Reverse transcriptase A: has 5ˊ → 3ˊ polymerase activity B: has 3ˊ → 5ˊ exonuclease activity C: is an RNA-dependent DNA polymerase D: is a DNA-dependent DNA polymerase
- DNA polymerase Ⅲ has a 5’→3’exonuclease activity A: 正确 B: 错误
- 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 ____________________.
- The most widely used polymerase in the PCR process is ( ). A: klenow fragment B: T4DNA polymerase C: Taq DNA polymerase D: Vent DNA polymerase
