A database that answers the question, charting telomere repeat sequences for all known species, is: http://telomerase.asu.edu/sequences_telomere.html For example in Yeast:
TTAGG telomeric repeats have been found in several insects. From Sahara, Marek & Traut (1): (TTAGG)n-containing telomeres were found in three Lepidoptera species, the silkworm Bombyx mori (in which the telomeric sequence was recently discovered), the flour moth Ephestia kuehniella, and the wax moth Galleria mellonella, in one species of ...
It seems that the current model is that recombination is the mechanism by which telomere length is maintained in the malaria vector Anopheles gambiae. Here is an exerpt of Roth et al paper that proposed the recombination mechanism: The insertion of a transgenic pUChsneo plasmid at the left end of chromosome 2 provided a unique marker for measuring the ...
In short, yes. The best way to think about ageing is as an accumulation of age-related disorders. Telomere loss is one of many cellular defects that accumulate with age. Other defects include oxidative stress, accumulation of amyloid proteins and metabolic dysfunction. While these are all likely related in some way, there is no evidence that specifically ...
