Questions & Step-by-Step Solutions

What is the primary purpose of the polymerase chain reaction (PCR)?
Correct Answer: To amplify a specific DNA segment.
  • Step 1: Understand that PCR stands for Polymerase Chain Reaction.
  • Step 2: Know that PCR is a laboratory technique used in molecular biology.
  • Step 3: Recognize that the main goal of PCR is to make many copies of a specific piece of DNA.
  • Step 4: Realize that by amplifying this DNA, scientists can study it more easily.
  • Step 5: Remember that this process allows for further analysis, such as genetic testing or research.
