Some Interesting Facts About Telomeres
In modern times, you see a lot of use for telomerase analysis technology (TAT) in the field of medicine. In a nutshell, this test is a biomarker that is capable of determining risks and early prognosis o of certain illnesses like cancer. The telomere length is the focus of this process, incorporating the careful evaluation and analysis of it. Telomere length has been noted to be an essential factor in age-related diseases. Telomeres may be used as an individual biomarker or in combination with other biomarkers. What makes analyzing telomeres much more convenient will have to be the fact that you can get it from various samples of the body. To understand more about telomerase analysis technology, it helps if you get to know telomeres first and foremost.

Age-related disorders are associated with the length of your telomeres as mentioned earlier. Getting older is a normal part of life. 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? Are normal human cells just following a pre-programmed timetable of biology? For sure, aging is caused by a combination of all these factors and many more.
One of the most highly supported theories of aging will have to be one that links the natural process to telomeres. Telomeres are essentially found in your DNA molecules at their end as tiny protective caps, which make up all of your chromosomes. Their main role is to ensure that the ends of your chromosomes don’t end up sticking to each other or fraying.
Telomeres also play a crucial role in ensuring that a person’s DNA is properly copied when cells divide. 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. This leads to the loss of some important genetic information. As cells divide regularly, you can expect these DNA strands to shorten.
Now, why do cells still get some DNA left after all the division that they go through? This part is where telomeres play a significant role. When it comes to telomeres, they have a similar DNA sequence that is repeated time and time again, making them somehow disposable after all this repetition. They serve the purpose of keeping the rest of your DNA protected. They function by not losing any other crucial genetic information even if they gradually get shorter over time.
Cells age when telomeres shorten as well as other factors. Cells cannot divide like they should when they have too short telomeres. If they reach a crucial point, the cell now becomes inactive that either make them accumulate damage they can’t fix or they simply die.
