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 …

Nov 21, 2025 · Telomerase is an enzyme that influences cell life span by adding organic compounds known as nucleotides to telomeres, segments of DNA located at the ends of chromosomes.

Dec 11, 2022 · Telomerase is a ribonucleoprotein structure comprising a functional RNA component and a catalytic reverse transcriptase component. The RNA component houses a template for the …

Mar 30, 2025 · In eukaryotes, telomerase, a telomeric enzyme includes a catalytic protein subunit known as telomerase reverse transcriptase (hTERT) and a core RNA component (hTR) that synthesizes …

Telomerase is a reverse transcriptase that adds repeats of a DNA sequence (TTAGGG) to the ends of chromosomes (telomeres) in mitotic cells, thus maintaining their length and preventing cell cycle …

Dec 19, 2024 · Telomerase is a ribonucleoprotein enzyme that maintains the protective telomere sequences at the ends of eukaryotic chromosomes by adding repetitive nucleotide sequences, …

Jul 30, 2025 · Telomerase itself is composed of two main parts: a catalytic protein subunit called telomerase reverse transcriptase (TERT) and an RNA component (TERC or hTR) that serves as a …

Each time a cell divides, the telomeres lose a small amount of DNA and become shorter. Over time, the chromosomes become damaged and the cells die. Telomerase helps keep this from happening. …

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 …

Jan 7, 2026 · This heterochromatin-amplification-mediated and telomerase-independent (HAATI) strategy relies on packaging of the terminal ribosomal DNA into heterochromatin, highlighting that …
