Question

what is gel electrophoresis? How is it done? What is it used for? What is the common name for it?

Answer 1

It is a method used to separate proteins by charge and/ or size and in molecular biology to separate a mixed population of DNA and RNA fragments by length, to estimate the size of DNA and RNA fragments or to separate proteins by charge. DNA Gel electrophoresis is usually performed for analytical purposes, often after amplification of DNA, but may be used as a preparative technique to use of other methods such as mass spectrometry, RFLP, cloning, DNA sequencing, or Southern blotting for further characterization. it is commonly named gel and maybe somehow it is related to DNA fingerprinting.
