Thus, telomere reactivation may have potential for treating age-related diseases in humans. 2020-12-05 2005-02-07 2013-01-15 In this sense, telomeres also play a critical role in preventing cancer, which is uncontrolled cell division. This is why we can’t just keep extending the lives of our cells by boosting telomere regeneration with more telomere-producing telomerase: our inbuilt cancer prevention systems would be compromised.

As a result, telomeres shorten during n o o mple-tion of DNA telomere repeats by telomerase [1]. This o mosome 3′e complementary strand is completed by DNA polymeras-. To merase is a ribonucleoprotein complex [2]. The o merase reverse transcriptase and teloA TELOMERES AND THEIR FUNCTIONS. Telomeres, unique structures at the physical ends of linear eukaryotic chromosomes, were first described almost 70 yearsago by Hermann Muller in his classic studies of the fruit fly Drosophilia melanogaster ().

. Telomeres are special sections of DNA that don’t contain genetic information but serve as caps so the ends of the chromosomes don’t fray. If the caps weren’t present the DNA would bind with other chromosomes and corrupt the genetic information stored in the DNA. Telomeres also function as part of cell’s aging and death process. Date: February 23, 2021 The telomere functions as a protector to the end of the chromosome.

What is the function of telomeres? Telomeres serve three main purposes: They helped organize each of our 46 chromosomes inside the nucleus (control center) of our cell.

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, nucleoprotein structures at chromosome ends, have a key role in the processes of cell senescence and immortalization (for a review, see references 3 and 4).In each cell division, telomere length is reduced as a result of incomplete end replication and degradation by a putative nuclease ().In somatic cells, this telomere shortening ultimately induces cell senescence ().
