Vedclass · Answer

(D) The telomeres are the terminal regions of eukaryotic chromosomes that protect the ends from degradation and fusion. These regions consist of highly conserved,repetitive $DNA$ sequences. In most eukaryotes,including humans,these telomeric sequences are characterized by a high content of $G$ (Guanine) nucleotides. For example,the human telomeric repeat sequence is $5'-TTAGGG-3'$,which is rich in Guanine. Therefore,telomeres are Guanine-rich.

The telomeres of eukaryotic chromosomes consist of short sequences rich in:
