Q. The telomeres of eukaryotic chromosomes consist of short sequences of
A) Thymine rich repeats
B) Cytosine rich repeats
C) Adenine rich repeats
D) Guanine rich repeats
Explanation
Telomeres have unique structures, including short nucleotide sequences present as tandemly repeated units. Clusters of G residues in one strand and C residues in the other characterise telomeric DNA. Also, in some species the telomeres terminate with a single-stranded DNA (12-16 nucleotides long) rich in guanine.
