Vedclass · Answer

(D) Telomeres are specialized structures at the ends of linear eukaryotic chromosomes consisting of repetitive $DNA$ sequences and associated proteins.During $DNA$ replication,the enzyme $DNA$ polymerase cannot replicate the extreme ends of the lagging strand because it requires an $RNA$ primer to initiate synthesis.If the ends of chromosomes consisted of essential genes,they would be lost during each round of cell division.Telomeres act as protective caps that prevent the loss of vital genetic information by allowing the chromosome to shorten slightly without affecting coding regions,thus preventing chromosome shortening and degradation.

Telomeric repetitive $DNA$ sequences control the function of eukaryotic chromosomes because they...
