Centromere vs. Kinetochore

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.

Kinetochorenoun

(biology) The protein structure in eukaryotes which assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis.

Kinetochore

A kinetochore (, ) is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. The kinetochore assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.
