Facts On Epigenetics And Genes In General

By Carl Rogers


Epigenetics is the study of changes in gene activity which is not caused by changes in the DNA sequence. DNA is what gives us our identity. It makes us unique from all the other people. We inherit it from our parents. Thus relatives have DNA that is similar in some ways. The article below points outs of genetics.

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.

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.

All living things on the face of the earth have a similar DNA structure. These are usually four bases. This is an implication of one of two things. All living things have a common ancestry, or these four bases are the only way that stable DNA can be formed. A slightly altered base structure was fed into cells which were incorporated as DNA. This means that our first ancestor decided on the base structure of our DNA.

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.
