This is used in electrophoresis to compare the DNA strands to the DNA standard. The negative control is used when no response is expected, which is also used in the process of electrophoresis. Electrophoresis is a technique used in laboratories in order to separate macromolecules based on size. It applies a negative charge so proteins move towards a positive charge. It is sued for the analysis of both DNA and RNA.
Yes it does because how it looks
