NEET BIOLOGY

Detailed explanation-1: -Gel electrophoresis is the process by which we take the DNA and run an electric charge through it, therefore we can use it to compare two DNA samples, hence the name DNA fingerprinting.

Detailed explanation-2: -All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only. Using electrophoresis, we can see how many different DNA fragments are present in a sample and how large they are relative to one another.

Detailed explanation-3: -Question 1: Which of the following statements about agarose gel electrophoresis is False? Electrophoresis in agarose is a common way to separate DNA molecules according to size. INCORRECT.

Detailed explanation-4: -Gel electrophoresis is used to isolate, identify, and characterize properties of DNA fragments in many different situations and at many different points during the cloning process. A small amount of DNA can be loaded into a well at one end of a gel in an apparatus that allows a current to be run through the gel.
