In gel electrophoresis, we cannot see pure DNA fragments in visible light and without staining. Explain how is it possible to visualize the DNA fragments?

The DNA fragments can be separated using gel electrophoresis. Write the name of technique used to remove the DNA from the gel.

Gel electrophoresis is a technique to separate fragments of DNA from a mixture. Some of the events of electrophoresis are given below. Arrange the events in order- (1) Cut out DNA bands. (2) Expose to UV. (3) Force DNA to move through gel. (4) Stain DNA to move through gel.

The DNA fragments can be separated using gel electrophoresis. Name the gel used in this technique.
