Telomerase is an ribonucleoprotein enzyme that works as a cellular reverse transcriptase that adds DNA in the chromosomal. It involves the protection of chromosome endings from getting shorter during replication of DNA to avoid the loss of catastrophic DNA. Related Theory Telomerase is a ribonucleoprotein molecule that is enzymatic in nature. It uses a special mechanism for the synthesis of DNA at telomeric ends. The DNA repeat sequence of telomere has one $G$-rich strand and other $C$ rich strand. The G-rich strand has a single stranded overhand. This overhand works as a primer and for its elongation uses as template the RNA component of telomerase enzyme. Thus, telomerase synthesizes only the G-rich strand of telomeres.
