Question

What does a gel electrophoresis migration pattern display?

1) Polymerase chain reaction
2) DNA sequencing
3) Protein synthesis
4) Gene expression

Answer 1

Gel electrophoresis migration pattern displays the separation of DNA fragments based on size. Shorter fragments migrate faster while longer fragments migrate slower.

Step-by-step explanation:

Gel electrophoresis migration pattern displays the separation of DNA fragments based on their size. Shorter DNA fragments migrate faster, while longer fragments migrate slower. The exact position of the fragments in the gel can be determined through autoradiography on a photographic film.
