Telomerase is an enzyme that is a:
Correct answer: C. Ribonucleoprotein
- A. Simple protein
- B. RNA
- C. Ribonucleoprotein
- D. Repetitive DNA
Explanation
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 another C rich strand. The G rich strand has a single stranded overhand. This overhand works as a primer and uses the RNA component of telomerase as its template for elongation. Thus telomerase synthesizes only the G rich strand of telomeres.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
