What is a Telomere

Question

What is a telomere?
A)the mechanism that holds two sister chromatids together
B)DNA replication during telophase
C)the site of origin of DNA replication
D)the ends of linear chromosomes
E)the RNA primer used during DNA replication

Accepted Answer

Telomeres are the ends of linear chromosomes which consist of repetitive DNA sequences that do not code for any specific genes. They protect the genetic content of chromosomes from degradation and fusion with neighboring chromosomes during cell division. Over time, as cells divide, telomeres become shorter, leading to aging and disease.
