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 prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the nucleoid. In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones.
