telomerase

(= telomere terminal transferase) A DNA polymerase with rather unusual properties that will only elongate oligonucleotides from the telomere and not other sequences. The enzyme contains an essential 159 residue RNA sequence that provides a template for the replication of the G-rich telomere sequences (so that the enzyme could in fact be considered a reverse transcriptase). ...

Telomerase

Telomerase also called telomere terminal transferase is a ribonucleoprotein that is an enzyme that adds DNA sequence repeats (`TTAGGG` in all vertebrates) to the 3` end of DNA strands in the telomere regions, which are found at the ends of eukaryotic chromosomes. This region of repeated nucleotide called telomeres contains noncoding DNA and hin......

telomerase

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. Cancer cells usually have more telomerase than most normal ...

telomerase

An enzyme that rebuilds telomeres. Telomerase is overexpressed in many cancer cells, and it contributes to their immortality, or ability to divide endlessly.

Telomerase

Telomerase: An enzyme concerned with the formation, maintenance, and renovation of telomeres, the ends of chromosomes. Telomerase regulates the proliferative capacity of human cells. Telomerase activation plays a critical role in the progression of cancer as well as in normal somatic cells. Failure to activate sufficient telomerase promotes disease...

telomerase

The enzyme that maintains the ends of chromosomes by catalysing for the synthesis of telomeres. Unlike many other enzymes, which are made of only proteins, telomerase also contains RNA – a nucleic acid like DNA but that has only a single strand.

telomerase

Type: Term Pronunciation: tel-ō′mĕ-rās Definitions: 1. A reverse transcriptase comprising an RNA template, which acts as a die for the TTAGGG sequence, and a catalytic protein component that is not found in normal, aging somatic cells.
