Gel electrophoresis is a laboratory method used to separate mixtures of DNA and RNA or proteins according to their molecular size.


This process is used by molecular biologists to :

1) separate a mixture of DNA and RNA fragments by length.

2) estimate the size of DNA and RNA fragments.

3) separate proteins by charge.

This process is also used in the field of forensics, genetics, microbiology and biochemistry.
Gel electrophoresis can also be used for separation of nanoparticles.
