Nucleus (as nuclear DNA),mitochondrial(mitochondrial DNA) and chloroplasts.
DNA is packed tightly around protein called Histones, in Eukaryotes cells;so that many molecules can easily be held together as chromosomes.
Chromosomes are thread-like structure in nucleus of cells.The histones provide support to the DNA molecule
The part DNA molecule coded for by a polypeptide is GENE, therefore in the nucleus of cells, DNA contains GENE,and the gene and DNA are packed in chromosomes,DNA appears as circular DNA mitochondria
They all have these traits: <span>Cellular organization, Reproduction, Metabolism, Homeostasis, Heredity, Response to stimuli, Growth and development, and <span>Adaptation through evolution.</span></span>
