- Telomerase - Wikipedia
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
- Telomerase | Description, Function, Facts | Britannica
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
- Telomeres and telomerase (article) | Khan Academy
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, meaning an enzyme that can make DNA using RNA as a template
- Telomeres and Telomerase: Structure and Functions - Microbe Notes
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 and maintains the telomere structure with uncontrolled cell growth and is linked to the development of cancer
- Telomerase - an overview | ScienceDirect Topics
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 arrest and cell death (cellular senescence)
- Telomerase – Structure, Mechanism, Regulation, Functions
Telomerase is a ribonucleoprotein enzyme that maintains the protective telomere sequences at the ends of eukaryotic chromosomes by adding repetitive nucleotide sequences, ensuring chromosome stability and preventing DNA degradation
- Regulation of human telomerase in homeostasis and disease
Telomerase is a ribonucleoprotein complex, the catalytic core of which includes the telomerase reverse transcriptase (TERT) and the non-coding human telomerase RNA (hTR), which serves as a
- Definition of telomerase - NCI Dictionary of Cancer Terms
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 Cancer cells usually have more telomerase than most normal cells
