<prompt> Telomerase-RNA polymeraseCauses carcinogenesisPresent in somatic cellsAbsent in germ cells  <response>: By using TERC, TE can add a six-nucleotide repeating sequence, 5-TTAGGG in veebrates, the sequence differs in other organisms to the 3 strand of chromosomes. These TTAGGG repeats with their various protein binding paners are called telomeres. The template region of TERC is 3-CAAUCCCAAUC-5. Telomerase can bind the first few nucleotides of the template to the last telomere sequence on the chromosome, add a new telomere repeat 5-GGTTAG-3 sequence, let go, realign the new 3-end of telomere to the template, and repeat the process. Telomerase reverses telomere shoening.
