Centromere vs. Centrosome — What's the Difference?

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.

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.

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

A small region of cytoplasm adjacent to the nucleus that contains the centrioles and serves to organize microtubules.

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

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

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

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.

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

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