All About Epigenetics And Genes Wholly

By Carl Rogers


Our DNA is what makes us so different from other people. Everyone has a unique set of genetic material which can help in identification. In DNA there is the section of epigenetics. This is the study of changes in gene activity that is not brought about by the change in the gene sequence. The article below elaborates on genes.

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.

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.

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.

There is the case of jumping genes. These are the king of genes that can detach themselves from a DNA strand and later on reattach themselves. These do not have many effects, and the effects are dominant in maize seeds. Many are times you may have seen that maize grains have a lot of different colors. These are a perfect example of jumping genes.

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.
