Answer 1

Electrophoresis is a technique commonly used in the lab to separate charged molecules, like DNA, according to size. Gel electrophoresis is a technique commonly used in laboratories to separate charged molecules like DNA?, RNA? and proteins?according to their size. ... Molecules migrate towards the opposite charge

Answer 2

Gel electrophoresis is used to separate macromolecules like DNA, RNA and proteins. DNA fragments are separated according to their size. Proteins can be separated according to their size and their charge (different proteins have different

Gel electrophoresis: Making the gel

Tasha is a Year 13 student who learnt how to make a gel at Genesis R&D in Auckland.

A solution of DNA molecules is placed in a gel. Because each DNA molecule is negatively charged, it can be pulled through the gel by an electric field. Small DNA molecules move more quickly through the gel than larger DNA molecules.

The result is a series of ‘bands’, with each band containing DNA molecules of a particular size. The bands furthest from the start of the gel contain the smallest fragments of DNA. The bands closest to the start of the gel contain the largest DNA fragments.
