Answer:
The correct answer is - Gel electrophoresis.
Explanation:
Gel electrophoresis is a lab technique used to separate distinct samples of mixed DNA, RNA, or proteins on the basis of their size. In gel electrophoresis, the molecules to be move from one another by an electrical field through a gel with small pores in it. DNA molecules are negatively charged so they move towards positive charge wells in the electric field and get separated.
The end product of the protein breakdown by the said enzyme, protease, are amino acids. Protease is an enzyme that is responsible for the digestion of different types of proteins. They breakdown proteins by hydrolysis. They are also called proteolytic enzymes.
Skin is covered by epithelial cells. Liver is mainly made up of hepatocytes though fibrous and fatty tissues are also present.<span>Cells of skin epithelium are present in different layers. Lower most layer on basement membrane (all epithelia possess this barrier on which epithelial cells grow) are newly generated. These cells gradually acquire a protective protein keratin but loses vitality. Thus by the time cells reach top most layer of skin they are all dead cells.</span>
