Which of the following is/are not essential to carry out the polymerase chain reaction?

a. primers
b. DNA polymerase
c. gel electrophoresis
d. high temperature

Expert Solution & Answer

Summary Introduction

Introduction:

PCR is a technique used to replicate and produce several copies of DNA. PCR has a wide application in research, medicine, agriculture, and many other fields.

Answer to Problem 1MCQ

Correct answer:

Gel electrophoresis is not essential to carry out polymerase chain reaction. Therefore, option (c) is correct.

Option (c) is given as “gel electrophoresis”.

Explanation of Solution

Justify reason for the correct statement:

PCR is a technique used to amplify DNA molecules. This technique involves three steps: denaturation, annealing, and extension. In denaturation, double stranded DNA is heated athigh temperature94 °C and converted into single stranded DNA. After conversion into single stranded, primers get annealed into single stranded DNA. After primer annealing, DNA polymerase enzyme bind to the 3′ end of primer and nucleotides which are complementary to template strand.

After polymerase chain reaction, the resulted fragments are run into gel electrophoresis. Gel electrophoresis is used to separate DNA fragments according to the molecular weight. Thus, gel electrophoresis is not essential to carry out PCR.

Hence, option (c) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “primers”.

Primers are essential to carry out the polymerase chain reaction. Hence, it is a wrong answer.

Option (b) is given as “DNA polymerase”.

DNA polymerase is important to synthesize DNA fragment. Hence, it is a wrong answer.

Option (d) is given as “high temperature”.

High temperature is required for denaturation of DNA. Hence, it is a wrong answer.

Hence, options (a),(b), and(d) are incorrect.

Conclusion

Gel electrophoresis technique is used after the PCR reaction. Gel electrophoresis technique is used to separate the amplified DNA fragments.

DNA polymerases make errors in matching as DNA is synthesized. These errors can be detected and repaired by: A. Ligase B. DNA polymerase C. Primase D. Helicase

Match the terms associated with the polymerase chain reaction with their correct descriptions. Refers to the fact that DNA molecules get longer the more of them there are in the reaction. A. В. Heat the sample to a high temperature (usually 94°C) to separate all DNA strands from each other. Denaturation C. Incubate the reaction at the optimal temperature for the primers to base-pair with each other. Annealing. D. Incubate at a low enough temperature (usually-55°C) so that primers base-pair with their complementary sequence. Extension. Add a chaotropic agent that destabilizes hydrogen bonding. E. Amplification. F. Incubate the sample at a temperature that is optimal for thermostable Taq DNA polymerase (usually -72°C). G. Happens after repeated cycles of the temperature change regimen. Refers to the quadrupling of the target DNA sequence in every cycle of the temperature regimen. Н.
