Genetic stability maintenance requires an extremely accurate mechanism for DNA replication and mechanisms for fixing the several accidental lesions that occur continually in DNA. Spontaneous changes in DNA are temporary due to immediate correction process called DNA repair. DNA repair’s importance is very evident from the huge investment that cells form in DNA repair enzymes. In 1000 accidental base changes in DNA , fewer than one results in a permanent mutation due to the efficient elimination by the DNA repair.<span> </span>
Collagen is the structural protein found in skin and connective tissue. This protein is the most abundant protein, that makes up one-third of the protein in the human body. The function of this protein in the skin is to give the skin strength and elasticity, and to replace dead skin cells. In connective tissues it s<span>upports structures and anchor cells to each other.</span>
