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 …

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 …

Some cells have the ability to reverse telomere shortening by expressing telomerase, an enzyme that extends the telomeres of chromosomes. Telomerase is an RNA-dependent DNA polymerase, …

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 …

Mar 18, 2026 · Telomerase is an enzyme that rebuilds the protective caps on the ends of your chromosomes. These caps, called telomeres, are stretches of repetitive DNA that shorten every time …

Mar 27, 2026 · A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At the heart of this protective process is an enzyme called …

Oct 26, 2025 · Telomerase is a specialized ribonucleoprotein enzyme that extends the ends of chromosomes by adding repetitive DNA sequences to telomeres. Its primary function is to counteract …

Jan 21, 2026 · Here the authors reported structures of human telomerase at three stages of telomeric repeat synthesis, providing key insights into its mechanism.

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. …
