The most commonly used polymerase is
A) Escherichia coli 37 DNA polymerase.
B) Taq DNA polymerase.
C) Mg DNA polymerase.
D) Dds DNA polymerase.

Question

Quizplus · Accepted Answer

Taq DNA polymerase is the most commonly used polymerase in PCR (polymerase chain reaction) due to its high processivity, thermostability, and ability to withstand high temperatures without denaturing. Escherichia coli 37 DNA polymerase is commonly used for in vitro DNA replication, but not in PCR. Mg DNA polymerase and Dds DNA polymerase are not commonly used polymerases.
