Aging Effects on Genetics

It is a common desire for everybody to be young and remain young. But that doesn’t happen so. Everybody undergoes the process called aging.

Aging is the inability to perform in with maximum efficiency and gradual deterioration of the ability. Aging cannot be surpassed or suppressed. It has to happen and it will happen. The aging process accompanies physical weakness, immune suppression and gene loss. The gene loss and gene repression is attributed to be the major cause of aging. As the aging progresses, the telomeres get shortened. The telomere is a part of chromosome and chromosomes are responsible for carrying genes. As the telomeres get shortened, there are some parts of the genes that get lost. This gene loss is permanent and the lost genes are lost forever.

The gene loss will result in the cell working below its potential and as a result will lead to further aging. There is also another genetic effect called as gene repression. Many genes send the signals to cells chemically on their function. When this path gets disturbed due to physical or physiological aspects, the information cannot travel and data loss occurs resulting in the cell losing its functionality. The repression might have happened due to damage done externally or because of disease attack. These are inevitable and occur somehow. These are the major genetic effects that occur due to aging. The other effects may be in DNA sequences. The DNA sequence gets altered and gets cut due to several factors. There are about 30000 genes in a normal human and due to gene loss, some hundreds of genes get lost due to aging.
