What are the telomeres and why are they important?

Telomeres, the specific DNA–protein structures found at both ends of each chromosome, protect genome from nucleolytic degradation, unnecessary recombination, repair, and interchromosomal fusion. Telomeres therefore play a vital role in preserving the information in our genome.

What is telomeres and its function?

Telomeres are specialized nucleoprotein structures located at the ends of linear chromosomes; they consist of TTAGGG repetitive sequences. They function to prevent natural chromosomal termini from activating the DNA damage response.

Where are telomeres found and what are their function?

Our chromosomes have protective structures located at their ends called telomeres. These protect our chromosomes by preventing them from damage or fusion with other chromosomes. Telomeres are made up of thousands of repeats of the same DNA sequence, bound by a special set of proteins called shelterin.

What is the function of telomeres and why are they important to us what can result in the loss of telomere function?

6.1. Telomeres are repetitive nucleotide sequences at each end of chromosomes. Their function is to protect the ends of the chromosomes from deterioration or fusion to other chromosomes during cell division. With every cell division, telomeres shorten. This blocks further cell division and induces senescence.

How can I test my telomeres?

The “flow-FISH” test, which stands for flow cytometry and fluorescence in situ hybridization, specifically measures the telomere length in each cell within a patient’s blood sample. The test was developed in 2006 by Canadian researcher Peter Lansdorp, M.D., Ph.

Why do we age telomeres?

Telomeres get shorter each time a cell copies itself, but the important DNA stays intact. Eventually, telomeres get too short to do their job, causing our cells to age and stop functioning properly. Therefore, telomeres act as the aging clock in every cell.

What is the main cause of aging?

Some aging is caused by the body. Think kids growing and teenagers going through puberty. Other aging accumulates over time, like skin damage caused by sun exposure. As a result, aging is a combination of bodily changes and the impact of how we take care of ourselves.
