One function of the telomeres in a chromosome is to
-
- indentify the correct number of the homologous pair of chromosomes
- help two chromatids to move towards poles
- "seal" the ends of chromosomes
- start RNA synthesis
Correct Option: C
Seal the ends of chromosomes. The telomere is a "ribonucleoprotein complex" composed of a protein component and an RNA primer sequence which acts to protect the terminal ends of chromosomes. This prevents chromosomal disintegration and prevents the ends of the chromosome from being processed as a double strand DNA break, which could lead to chromosome-tochromosome telomere fusions.
