Question

What does gel electrophoresis reveal about DNA?

Answer 1

The size of the fragment of DNA can be revealed in gel electrophoresis

Explanation:

Electrophoresis is a process by which an electric field is used to move the DNA fragments through porous agarose gels.

The smaller fragments move faster than the larger ones. The sizes can be estimated by comparing their positions in gel to positions of DNA molecules whose sizes are known.
