THEORIES OF AGING. The Somatic Mutation Theory of Aging

This theory states that an important part of aging is determined by what happens to our genes after we inherit them. From the time of conception, our body's cells are continually reproducing. Each time a cell divides, there is a chance that some of the genes will be copied incorrectly, this is called a mutation. Additionally, exposures to toxins, radiation or ultraviolet light can causes mutations in your body's genes. The body can correct or destroy most of the mutations, but not all of them. Eventually the mutated cells accumulate, copy themselves and cause problems in the body's fnctioning related to aging.
