Centriole vs. Centromere — What's the Difference?

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.

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.

One of two cylindrical cellular structures that are composed of nine triplet microtubules and form the asters during mitosis.

The most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.

(biology) A barrel-shaped microtubule structure found in most animal cells, important in the process of mitosis (nuclear division).

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

One of two small cylindrical cell organelles composes of nine triplet microtubules, which form the asters during mitosis.

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