PCR Overview

What is the purpose of Polymerase Chain Reaction (PCR)?

• The purpose of Polymerase Chain Reaction (PCR) is to amplify specific DNA sequences.

• The purpose of Polymerase Chain Reaction (PCR) is to analyze weather patterns

• The purpose of Polymerase Chain Reaction (PCR) is to separate proteins

• The purpose of Polymerase Chain Reaction (PCR) is to measure blood pressure

List the three main steps involved in PCR.

• Heating, Cooling, Amplification

• Mixing, Filtering, Reading

• Separation, Purification, Detection

• Denaturation, Annealing, Extension

How is DNA denaturation achieved in PCR?

• By adding more DNA

• By heating the DNA to around 95°C

• By exposing the DNA to light

• By freezing the DNA

What is the significance of PCR in genetic research?

• PCR enables the amplification of specific DNA sequences for analysis in genetic research.

• PCR is used to study plant biology only

• PCR is not relevant in genetic research

• PCR is primarily used for weather forecasting

Explain the role of primers in PCR.

• Primers in PCR help initiate DNA synthesis by providing a starting point for DNA polymerase to bind and begin copying the target DNA region.

• Primers in PCR help in protein synthesis.

• Primers in PCR are only necessary for RNA amplification.

• Primers in PCR are used to detect mutations in DNA sequences.

What are some common applications of PCR in the field of medicine?

• Diagnostic testing, genetic testing, infectious disease detection, forensic analysis, research

• Vaccine development, food safety testing, environmental monitoring

Why is PCR considered a revolutionary technique in molecular biology?

• PCR is considered revolutionary in molecular biology because it enables the rapid amplification of specific DNA sequences.

• PCR is considered revolutionary in molecular biology because it can only be performed by highly specialized technicians.

• PCR is considered revolutionary because it involves the use of radioactive materials.

• PCR is revolutionary due to its ability to sequence entire genomes in a single step.

Describe the process of DNA amplification in PCR.
