what causes gray hairs?
In: Biology
Part of how our bodies keep everything working is by making new cells. When this happens a new cell forms out of the old one resulting in 2 cells. The new cell needed to copy the DNA from the old cell, because DNA is the instruction manual for the cell. During the copy process, the new DNA will sometimes lose a codon, which is basically the last page of the manual. Over time this leads to things like hair losing color or moisture because the cells forgot how to produce the proper proteins, or skin losing elasticity because the cells forgot how to make collagen. That’s what causes aging.
