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.

Inbreeding is one of the many causes of the loss in value breeds be it be plants or animals. It may lead to characteristics such as stunted growth, slow development generally among other things. Even in people, people are not allowed to marry relatives in many cultures. Some of Muslims, however, do not mind marriage between cousins.

Mosaicism is a condition where by cells mutate and form a whole new line of DNA. For embryos, it could happen when they are 8-16 cells old. It may also occur in the case of twins. The embryos tent to interact and later grow as separate individuals with two kinds of DNA. The organism after having patches of each DNA is referred to as a chimera.

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.

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 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.

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.
