The telomeres of eukaryotic chromosomes consist of short sequences of:
Correct answer: D. Guanine rich repeats
- A. Thymine rich repeats
- B. Cytosine rich repeats
- C. Adenine rich repeats
- D. Guanine rich repeats
Explanation
Telomeres are characterized by guanine-rich repeats, which play a key role in protecting chromosome ends and maintaining genome stability. These sequences form structures like G-quadruplexes, crucial for telomere function .
