Webreverse transcriptase, telomerase (Blackburn 1991). However, several cell types have been found that maintain their chromosome ends in the absence of telomerase. These cells use telomerase-independent pathways to maintain their telomeres, including the alternative lengthening of telomeres (ALT) pathway. ALT and ALT-like pathways have been found WebDec 18, 2002 · At present, the only evidence of a telomerase component encoded by a virus is the telomerase protein component of the temperate Escherichia coli phage N15, which plays a critical role in the replication of this bacteriophage by a cleaving-joining activity (11, 37). We report here for the first time the identification of an RNA telomerase gene ...

WebTelomerase is perceived as an immortality enzyme that might provide longevity to cells and whole organisms. Importantly, it is generally inactive in most somatic cells of healthy, adult men. Consequently, its substrates, i.e. telomeres, get shorter in most human cells with time. WebTelomerase allows these cells to divide many times without becoming damaged or undergoing apoptosis. Telomerase is also abnormally active in most cancer cells, which …
