Question

Telomerase is a ribonucleoprotein that is an enzyme which adds DNA sequence repeats ("TTAGGG" in all vertebrates) to the 3' end of DNA strands in the telomere regions, which are found at the ends of eukaryotic chromosomes. It ___________________________________.

a. can synthesize telomere DNA without a primer.
b. carries its own RNA molecule as a template for telomere extension.
c. uses a protein as a primer to extend the telomere.
d. is a RNA polymerase.
e. none of the above.

Answer 1

Telomerase is an enzyme that carries its own RNA molecule as a template for telomere extension, allowing it to synthesize telomere DNA without a primer.

Step-by-step explanation:

Telomerase is an enzyme that adds DNA sequence repeats to the 3' end of DNA strands in telomere regions. It carries its own RNA molecule as a template for telomere extension, allowing it to synthesize telomere DNA without a primer. This process helps maintain the integrity and length of telomeres, which protects the genes from getting deleted as cells divide.
