Question

Which of the following technique is employed to check the progression of a restriction enzyme digestion?

• A. PCR
• B. Bioreactor
• C. Gel electrophoresis
• D. Micro injection

Answer 1

The correct option is C Gel electrophoresis

Answer is option C i.e. "Gel electrophoresis"
Gel electrophoresis is the technique which can check DNA fragment progression. Restriction enzyme digest DNA into fragments. Each fragment has different size. When gel electrophoresis is performed each fragment with different sizes are separated on the gel.
While, PCR is used for DNA amplification. Bioreactors are the fermentors used for fermentation process and micro-injection is a method used to transfer genes between animals.
