Explain polymerase chain reaction (PCR) testing.
DefinitionExplanation should include the concepts that PCR testing is a relatively quick procedure for analyzing deoxyribonucleic acid (DNA) without the need for cloning and that it is commonly used for diagnosing genetic diseases.
- What is a nucleotide? What is the role of nucleotides in PCR testing?
- Why are amino acid sequences important in PCR?
- How can a DNA segment be replicated?
- What was the purpose of the Human Genome Project?
