Answer   Chromosomes are located in the nucleus of a cell in eukaryotes. In prokaryotes (which lack a cell nucleus) chromosomes are circular in shape usually found â¦ attached to the plasmid membrane.
In eukaryotic cells, like in the maize cell shown here, DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. 2  It is present in this compartment in the form of linear chromosomes that together constitute the genome. 3  These chromosomes are identical and equal in number in all cells of an individual (except reproduction cells and mutated cells).
