1.5 Chromosomes and chromatin
The DNA is usually dispersed in the nucleus as chromatin, but during mitosis and meiosis it becomes condensed and forms into a number of approximately cylindrical structures, the chromosomes.
Chromosomes are the DNA-containing structures of eukaryotic nuclei that form during the process of cell division.
