Practicing Success
Read the following passage and answer the questions that follow:- |
Taq polymerase synthesises DNA region between the primers using which of the following? |
Mg2+ dNTPs DNA ligase Both 1 and 2 |
Both 1 and 2 |
The correct answer is Option (4) -Both 1 and 2 The final step of PCR is the extension, wherein Taq DNA polymerase (isolated from a thermophilic bacterium Thermus aquaticus) synthesizes the DNA region between the primers, using dNTPs (deoxynucleoside triphosphates) and Mg2+. |
