Question

Agarose gel electrophoresis separates DNA molecules of size

a) 10 – 20bp b) 20 – 30bp

c) 100 – 20000bp d) 100 – 200bp​

Answer 1

Answer:

Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
