It better know - Telomere DNA Structure

DNA can be defined as a special nucleic acid that contains instructions for the development of the different features and among members of the family of the living organism. Its main function is to store information about the organization. The carrier of genetic information of a person or to another living organism in the hereditary is called genes. In each living body, there are some cells where is DNA and DNA form a helical shape and form chromosomes. The multiplication of these cells can also be called cell division and DNA replication. There are many structures of DNA and one of them is the Quadruplex. In it, there are linear-shaped chromosomes. End of these chromosomes are a very important area called Telomeres. This special Telomere DNA structure essentially protects the end of chromosomes.

It is very important to learn more about Telomeres and it will be easy to understand DNA Telomere structure. Firstly, the Telomeres are still present in parts of the end of chromosomes. It can be defined as a region of recurrent DNA in chromosomes at the end. Its main function is to protect or to occupy chromosomes end points to weaken or damage. Stop this region of end of deprivation or ruin genes. It does short-circuit at the ends of each chromosome is automatic in the replication process. The cell division process, there are enzymes which help to DNA replication. It was found that if cells divide without Telomeres, the tips of chromosomes would degrade and late lose information instructions it contains. Arguably remains at the end of block chromosomes and cell division-divide and gets recharged by enzymes special Telomeres. In this way there are many know the Telomere DNA structure.

There are various changes in the structure of Telomere DNA. There are two types of structures. extended and shortened. Shortening of Telomeres of human beings humans can cause replication, which can stop cell division and may affect the health of the person. While it protects by multiplying the cancer cells to grow, it can affect the immune system in humans and may increase the chances of having cancer. This shrinkage can occur due to aging and poor health. Also shortening can reduce cell division or the duplicity and skip to senescence may remove cancerous cells. Shortening could be corrected by giving long Telomeres. The other DNA Telomere structure is long Telomeres which raises power consumption. causing less energy after all a few hours. It seems not so bad, but it is very difficult to manage. Similarly, if certain conditions long Telomeres are in, while they can be cured by shorter Telomeres. But it the legacy of a person will not protect against cancer.

DNA is one of the smaller parts of our body and shape chromosomes have a very important link with the birth of the child and the genes. These chromosomes are the ends of each strand of chromosome Telomeres. They are very important and useful. They protect and store all information of the genes and take care of the duplicity. Telomere DNA structure may vary, but each change in the structure leads to disease in humans. Some scientists say that some changes may healing and slowing the ageing but has not yet been proven in humans. It is best to know everything about Telomeres arriving at conclusions.
