Telomere telomere recombination provides an express pathway for telomere acquisition
Nature, 1990DNA termini from Tetrahymena and Oxytricha, which bear C4A2 and C4A4 repeats respectively, can support telomere formation in Saccharomyces cerevisiae by serving as substrates for the addition of yeast telomeric C1-3A repeats. Previously, we showed that linear plasmids with 108 base pairs of C4A4 DNA (YLp108CA) efficiently acquired telomeres, whereas ...

The role that telomere biology may play in the human ageing process is of a significant interest to many laboratories around the world. In this, the first of a series of yearly reviews on telomeres and ageing, I review a small selection of papers published between July 2005 and June 2006 that maybe of direct relevance to the gerontology research ...

Telomeric noncoding
AbstractTelomeres are nucleoprotein structures that cap the ends of eukaryotic chromosomes, protecting them from degradation and activation of DNA damage response. For this reason, functional telomeres are vital to genome stability. For years, telomeres were assumed to be transcriptionally silent, because of their heterochromatic state.

Current Opinion in Cell Biology, 1991
Telomeres are essential for chromosome stability and replication. Maintaining a balance between telomere shortening and lengthening is essential for cell viability. Recent work on telomeres from yeast, Drosophila and mammals, and on telomerase has provided insight into the mechanisms of both the shortening and lengthening processes.

Telomeres are specialized structures at the ends of eukaryotic linear chromosomes, consisting of protein-bound tandemly repeated simple DNA sequences. Telomeric DNA is unique in that it is copied from an RNA template that forms part of the enzyme, telomerase. This review discusses the synthesis and maintenance of these unusual structures.

The ends of chromosomes consist of a hexanucleotide DNA repeat sequence and specialized DNA-binding and telomere-associated proteins. An enzyme activity called telomerase maintains telomere length by using an RNA template (TR) and a reverse transcriptase (TERT) to add the hexanucleotide sequence to the free chromosome end. The structure of telomeres is
