The telomeres of eukaryotic chromosomes consist of short sequences of:
The telomeres of eukaryotic chromosomes consist of short sequences of:
thymine rich repeats
cytosine rich repeats
adenine rich repeats
guanine rich repeats.
Solution
The ends of eukaryotic chromosomes contain repetitive DNA sequences called telomeres, which help to ensure that no information is lost from chromosome ends during DNA replication, rich in guanine repeats.
Related Theory
A highly conserved repetitive DNA sequence, (TTAGGG)n, present at the telomeres of human chromosomes. Each time a cell divides, the telomeres become shorter.
