- 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: Definition, Function, Structure and Cancer - Biology Dictionary
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: structure, functions, and activity regulation
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 is strictly limited and senescence follows approximat …
- Telomerase | Description, Function, Facts | Britannica
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 of repeats determines the maximum life span of a cell
- Telomeres and telomerase: three decades of progress
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
- 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
- Definition of telomerase - NCI Dictionary of Cancer Terms
An enzyme in cells that helps keep them alive by adding DNA to telomeres (the ends of chromosomes) 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
