Answer:

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
