Epigenetics And Genes As A Whole

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.

In DNA proteins are coded in three base layers. After the coding, there is a proof-reading process to ensure that no mistakes were made. The main aim is to make sure the copy is the same as the original. Mistakes may lead to conditions such for example; Haringtons disease. This is whereby there is a duplication of CAG which becomes a problem when passed on for generations.

Millions of years ago, a virus invaded the human body and has been a part of the human DNA for a long time now. A virus may invade the body cells. If mutagens are activated, it may be stopped completely but remain in the cell. Every time the cell is copied, the virus moves on to another cell. If it somehow comes in contact with a reproductive cell, the virus will be all over the individual.

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 first ancestor of all of the living organism is the determinant of the structural base of all the DNA. The bases are usually four, but some cells with different kinds of bases have been brought forth and still work normally. This dismisses the theory of DNA only being able to form on four base stands. It is possible that all living things share a common ancestry.

There is the possibility of three-parent babies. This may be really confusing, but it does not involve three individuals. A person gets half their chromosomes from their father and the half from their mother. The mitochondria, however, are all from their mother. If they have mutated, they may bring a problem and this may be solved by putting the nucleus into a none fertilized egg.
