They can turn some genes off or on at some point. It is an external modification of DNA. Epigenetics, are traits that are above all the genes. It does not affect the sequence of the DNA, but it does how the DNA reads. It may live in the body of a person for as long as some cells are still alive. In others, it lasts in their life time from childhood to adulthood. It may also be passed over generations.
It alters the physical structure of the DNA. An example of such a change is DNA methylation added to a methyl group or what is otherwise referred to as a chemical cap. This actually suppresses certain genes from being expressed. So the sequence of the DNA will appear the same, but the physical appearance of the organism will appear different.
DNA is very long. It would not be able to fit into a cell was It not for a protein known as histone. DNA does not squash the protein, however. It lays out itself comfortably. If the DNA is too tight, it will be impossible to read because of the DNA reading cells. The modifications make the histone relax, and the material is easier to read.
Various genes express themselves differently depending on how strong and their functionality at different intervals. This is why the skin cell, brain cells, and muscle cells appear to be very different yet they have the same genetic composition. The fact that these cells are different is the reason why our body parts are also different. They, however, work together in order to conduct bodily functions and to the purpose they are intended to undertake on that instant.
Epigenetics may actually be passed on to the next generation. This may happen if they are present in the sperm or egg cell or both. However, the epigenetics are erased when the sperm and egg combine to form a fertilized egg. This process is called reprogramming. It is where the cells of the fetus are given a chance to form their own epigenetics.
Some of the sperm and egg cells do not go through this reprogramming process. This means the fetus will reserve this epigenetic cells. Once the egg is fertilized, and reprogramming does not occur, the epigenetics are carried on to the next generation. This means the foods taken before conception play a big role in the future of your child. This is however not yet proved in human beings.
Scientists seem to have the idea that some epigenetics have the ability to control cancer. Some epigenetics may suppress the ability of a cell to control its growth. The cell overgrows and begins to hinder the normal functioning of the body and the others surrounding it. This is what comes to be a tumor.
There are also cells that suppress the growth of genes that could help repair damaged DNA. This cause the immune system to be weak. The person will be at the risk of contracting diseases. Cancer will also have a very easy opportunity to inhabit the body of the search of a person.
