Questions & Step-by-Step Solutions

What is a potential limitation of PCR?
  • Step 1: Understand what PCR is. PCR stands for Polymerase Chain Reaction, a method used to make many copies of a specific DNA segment.
  • Step 2: Know that PCR needs DNA to work. The DNA used must be of good quality.
  • Step 3: Learn about contaminants. Contaminants are unwanted substances that can mix with the DNA.
  • Step 4: Realize that if the DNA has contaminants, it can stop PCR from working properly.
  • Step 5: Understand that if PCR doesn't work well, the results can be incorrect or unreliable.
