Abstract
Telomeres are the ends of linear chromosomes end protect them from degradation and recombination. When a cell divides, telomeres are shortened, but to avoid telomere attrtion, germ-line and some somatic cells express telomerase, an enzyme that elongates telomeres. Telomerase complex is composed of a reverse transcriptase enzyme, TERT, an RNA component, encoded by TERC, and associated prot…
