2017年7月25日 · Telomerase is an enzyme found inside our cells, which may be related to the aging process. It adds short, repetitive “caps” to our DNA strands. These caps are called “telomeres.”

Telomerase, also called terminal transferase, [1] is a ribonucleoprotein that adds a species-dependent telomere repeat sequence to the 3' end of telomeres. A telomere is a region of repetitive sequences at each end of the chromosomes of most eukaryotes.

2022年12月11日 · Telomerase is a ribonucleoprotein structure comprising a functional RNA component and a catalytic reverse transcriptase component. The RNA component houses a template for the synthesis of telomeric DNA.

Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells. In human somatic cells proliferation potential …

telomerase, enzyme that influences cell life span by adding organic compounds known as nucleotides to telomeres, segments of DNA located at the ends of chromosomes. Telomeres consist of repetitive DNA sequences wherein the number …

2024年12月23日 · Telomerase (terminal transferase) is a ribonucleoprotein enzyme that extends telomeres, the repetitive nucleotide sequences at the ends of eukaryotic chromosomes. Telomeres function as protective caps, stopping chromosome ends from being erroneously perceived as DNA damage or from bonding with neighboring chromosomes.

2019年2月13日 · Three decades ago, the classic view was that telomeres protected the natural ends of linear chromosomes and that telomerase was a specific telomere-terminal transferase necessary for the...

Telomerase is a reverse transcriptase specialized in the addition of telomeric DNA repeats onto the ends of chromosomes. Telomere extension offsets the loss of telomeric repeats from the failure of DNA polymerases to fully replicate linear chromosome ends.
