Question: What is the function of the Taq polymerase in PCR? (2023)

Options:

Correct Answer: To synthesize DNA

Exam Year: 2023

Solution:

Taq polymerase is a heat-stable enzyme used in PCR to synthesize new DNA strands by extending primers during the amplification process.

What is the function of the Taq polymerase in PCR? (2023)

Step 1: Understand that PCR stands for Polymerase Chain Reaction, which is a method used to make many copies of a specific DNA segment.
Step 2: Know that Taq polymerase is an enzyme that helps in the process of PCR.
Step 3: Realize that Taq polymerase is special because it can work at high temperatures, which is important for PCR.
Step 4: Learn that during PCR, primers (short pieces of DNA) are added to the DNA to mark where to start copying.
Step 5: Understand that Taq polymerase attaches to these primers and starts adding new DNA building blocks to create new DNA strands.
Step 6: Remember that this process of copying DNA is repeated many times to make millions of copies of the target DNA.
