Gel electrophoresis is a technique used to separate DNA fragments according to their size. This is from Khan academy so I believe it is reliable.
The genetic code is directly related to polypeptides and proteins in the sense that genes are decoded to synthesize proteins.
What is the genetic code?
Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.
The genetic code is unique for living organisms and is used to synthesize the proteins that is responsible for various activities in living organisms.
The genes in the genetic code are first transcribed into mRNA, which is then translated into proteins (polypeptides).
