Centromere vs. Telomere

Centromerenoun

(genetics) The central region of a eukaryotic chromosome where the kinetochore is assembled.

Centromerenoun

a specialized condensed region of a chromosomes that appears during mitosis where the chromatids are held together to form an X shape.

Centromerenoun

a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape;

Centromere

The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad). During mitosis, spindle fibers attach to the centromere via the kinetochore.

Telomerenoun

(genetics) Either of the sequences of DNA at each end of a eukaryotic chromosome.

Telomerenoun

either (free) end of a eukaryotic chromosome;

Telomere

A telomere ( or , from Ancient Greek: τέλος, romanized: télos, lit. 'end' and Ancient Greek: μέρος, romanized: méros, lit. 'part') is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes. Although there are different architectures, telomeres, in a broad sense, are a widespread genetic feature most commonly found in eukaryotes.
