Centromere vs. Centrosome

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.

Centrosomenoun

(cytology) An organelle, near the nucleus in the cytoplasm of most organisms, that controls the organization of its microtubules

Centrosomenoun

A peculiar rounded body lying near the nucleus of a cell. It is regarded as the dynamic element by means of which the machinery of cell division is organized.

Centrosomenoun

small region of cytoplasm adjacent to the nucleus; contains the centrioles and serves to organize the microtubules

Centrosome

In cell biology, the centrosome (Latin centrum 'center' + Greek sōma 'body') (also called cytocenter) is an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell, as well as a regulator of cell-cycle progression. The centrosome provides structure for the cell.
