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.

There is a condition in which organism mutate and form a completely new strand of DNA. It is known as Mosaicism. For example, an embryo may mutate when it only has 8-16 cells. In twins, the two embryos may interact with each other before separating and coming up with completely new DNA strands. Such an organism has patches of different DNA and is known as a chimera.

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.

There is the possibility of viruses invading the human cells is very real. They can be very harmful if they are not affected by mutagens. Even when affected by mutagens they can be stopped but not completely eradicated from the cell. This means they will have passed on from one cell to another and if they come into contact reproductive cells, the individual may have the virus in all the cells.

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.

An individual gets their chromosomes from both parents. Mitochondria, however, they get from only the mother. If the cells have mutated, it may pose a big problem. This can be solved by transferring the nucleus from a fertilized egg to one that is not fertilized.
