4. The protective repetitive nucleotide sequences caps located at the extreme ends of eukaryotic linear chromosomes are known as

A. Kinetochores
B. Telomeres
✓
C. Centromeres
D. Nucleolar organizers

📝 Explanation

Telomeres are highly specialized, non-coding repetitive DNA sequences found at the terminal tips of linear chromosomes that protect them from degradation and end-to-end fusion.
