A) simple protein
B) RNA
C) ribonucleoprotein
D) repetitive DNA
Correct Answer: C
Solution :
[c] Telomerase is a ribonucleoprotein which synthesize the grich strand of telomeres in DNA. Telomerase is an enzyme that adds specific DNA sequence repeats (?TTAGGG? in all vertebrates) to the 3' ("three prime") end of DNA strands in the telomere regions, which are found at the ends of eukaryotic chromosomes. The telomeres contain condensed DNA material, giving stability to the chromosomes. The enzyme is a reverse transcriptase that carries its own RNA molecule, which is used as a template when it elongates telomeres, which are shortened after each replication cycle. Telomerase was discovered by Carol W. Greider in 1984.
