Centriole vs. Centromere
Centriolenoun
(biology) A barrel-shaped microtubule structure found in most animal cells, important in the process of mitosis (nuclear division).
Centriolenoun
one of two small cylindrical cell organelles composes of nine triplet microtubules, which form the asters during mitosis.

Centriole
In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells, but are not present in conifers (Pinophyta), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo.
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.
