Noteworthy Facts About Telomeres
These days, there are various reasons why testing using telomerase analysis technology (TAT) is becoming popular. In essence, this test is used as a biomarker to provide early prognosis and risk of certain health conditions like cancer. The telomere length is the focus of this process, incorporating the careful evaluation and analysis of it. There is a link between the length of telomeres and various age-related diseases. Telomeres may be used as an individual biomarker or in combination with other biomarkers. Telomeres are very convenient biomarkers because you can get them from various body samples. If you have plans of using telomerase analysis technology, you have to first get to know telomeres and what they are all about.

As mentioned above, the length of your telomeres is associated with age-related disorders. Aging is a normal life occurrence. To this day, many scientists are still puzzled over why people age and what causes aging. Different scientists come up with different theories like DNA damaged by oxidative stress. Should glucose be blamed as well? What about the cells of the body just all along following a biological timetable that is pre-programmed? While there are many theories, one thing is for sure: there are many causes of aging.
If you look at one theory that resonates a lot, it would have to be that telomeres are associated with the aging process. Telomeres are essentially found in your DNA molecules at their end as tiny protective caps, which make up all of your chromosomes. Their main responsibility is to stop the ends of chromosomes from sticking together or fraying.
Another role that telomeres play is to ensure that during cell division, a person’s DNA will be copied correctly. Sadly, in the process of DNA replication, there are instances where a few of the DNA building blocks or nucleotides found at the end of the strand are not copied into the new DNA. The outcome will be a loss of some crucial genetic information. DNA strands naturally shorter with every division of the cells.
So, how come cells still have some DNA left after the division they’ve undergone? This is where the role of telomeres comes in. Telomeres comprise the same DNA sequence repeated time and time again, making them somehow disposable. They play a role in ensuring that the rest of the DNA does not get damaged. Even if they get shorter time and time again, they will make sure not to lose your genetic information.
With the role of telomeres, when they shorten, they can be a factor that associates with the aging of cells. By the time your telomeres get too short, your cells will not be able to divide as effectively. Once these cells reach a crucial point, the cell will no longer be active making it either die or slowly accumulate some damage that it cannot fix.
