Telomerase
Telomerase also called telomere terminal transferase is a ribonucleoprotein that adds the nucleotide ""TTAGGG"" to the 3' end of telomeres, which are found at the ends of eukaryotic chromosomes. A telomere is a region of repetitive sequences at each end of a chromatid, which protects the end of the chromosome from deterioration or from fusion with neighbouring chromosomes.Telomerase is a reverse transcriptase enzyme that carries its own RNA molecule (with the pattern of ""CCCAAUCCC"" in vertebrates), which is used as a template when it elongates telomeres.
