All About Epigenetics And Genes Wholly

By Carl Rogers


This is the study of change in gene activity that is not brought about by the change in the gene sequence. As much as we get our DNA from our parents, at no point will our DNA be similar to that of other people whether we are related or not because this the distinguishing factor in human beings. It can be used for identification and even record keeping in human genes and related factors. The article shades more light on genes and epigenetics.

In both plants and animals, it is not advisable to cross-breed related ones. This is because it may bring complications despite both parents being in good health. This is usually because the DNA is very similar. The result of relatives coming together is usually offspring that have some defective characteristics thus closely related organisms should be separated.

A chimera is one is an organism with patches of different DNA. This may occur as a result of mosaicism which is a process by which genes mutate and form a whole new strand of DNA. An embryo of about 8-16 cells old faces the possibility of undergoing this process. In the case of twins, they may interact and form DNA before they become separate individuals.

Much like any other process, the coding of proteins cells in the body requires proof-reading to ensure no mistakes were made. The copies should be exactly the same as the original copy. Mistakes may lead to conditions such as Haringtons disease. This is because of excessive accumulation of CAG. It may not be a problem, but the disease becomes more prominent over generations.

Many are times when a virus invades the body; it goes on to the cell. When it is integrated, a mutation may occur thus deactivating the virus. The virus, however, remains in the genome and replicates every time the cell is copied. If it is copied into a sperm or ovum cell, then the cells of the embryo will all have the virus thus building an incorporated virus over tome.

You may have looked at a maize cob that happens to have different colored grains on it. The cob has usually not decided to put on makeup. The condition is known as jumping genes. This is a condition where why by various some genes have decided to detach themselves from the DNA strand and may come back later.

The DNA of all of the living organism is usually formed on four base strands. This may lead to you thinking that the only four DNA to exist is through this four base strands. This was however proved wrong where there were surviving cells with completely different DNA structures. This means that all living things have a common ancestor who decides the base structure of their DNA.

There is the possibility of a three-parent babies. An embryo gets half genes from the mother and half from the father. The mitochondria, however, come from the mother solely. If they are mutated, then it could raise problems. This can be fixed by normal fertilization taking place but the nucleus is removed and placed into a new egg that does not have a nucleus.
