PCR and Gel Electrophoresis

What does PCR stand for?

• Polymerase Chain Replication

• Polymerase Chain Reagent

• Protein Chain Reaction

• Polymerase Chain Reaction

What is the purpose of denaturation in PCR?

• The purpose of denaturation in PCR is to combine the single strands of DNA into double-stranded DNA.

• The purpose of denaturation in PCR is to separate the double-stranded DNA into single strands.

• The purpose of denaturation in PCR is to break down the DNA into individual nucleotides.

• The purpose of denaturation in PCR is to amplify the DNA strands.

What is the temperature range for denaturation in PCR?

• 94°C - 98°C

• 60°C - 65°C

• 80°C - 85°C

• 100°C - 105°C

What is the purpose of annealing in PCR?

• To denature the DNA strands

• To amplify the DNA sequence

• To separate the DNA fragments

• To allow the primers to bind to the target DNA sequence.

What is the temperature range for annealing in PCR?

• 70°C - 80°C

• 50°C - 65°C

• 30°C - 40°C

• 90°C - 100°C

What is the purpose of extension in PCR?

• To synthesize new DNA strands using DNA polymerase enzyme and the primers as templates.

• To separate the DNA fragments by size

• To denature the DNA strands

• To amplify a specific DNA sequence

What is the temperature range for extension in PCR?

• 68°C - 72°C

• 50°C - 55°C

• 75°C - 80°C

• 60°C - 65°C

What is the main enzyme used in PCR?

• Taq polymerase

• Ligase

• RNA polymerase

• DNA polymerase

What is the function of the DNA template in PCR?

• Provide a template for RNA amplification

• Provide starting material for DNA amplification

• Act as a primer for DNA synthesis

• Serve as a catalyst for the PCR reaction

What is gel electrophoresis used for?

• Gel electrophoresis is used to measure the concentration of DNA.

• Gel electrophoresis is used to determine the sequence of DNA.

• Gel electrophoresis is used to separate and analyze DNA, RNA, or proteins based on their size and charge.

• Gel electrophoresis is used to amplify DNA sequences.
