Show Answer
Answer : c
Hints & Solution
(c) The telomere is a region of repetitive nucleotide sequences at each end of a chromosome 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-to-chromosome telomere fusions.
