Summary Introduction
To review:
The definition of the following terms: centromere, kinetochore, telomere, chromatid, and spindle.
Introduction:
The nucleus of eukaryotic cell contains chromosomes, which are in the form of condensed chromatin. A chromosome consists of structures other than the gene, which is visible during the cell division only. These structures are centromere, telomere, kinetochore, and spindle fibers.
