in eukaryotic cells chromosomes are composed of
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.Humans inherit one set of chromosomes from their mother and a second set from their father.ach eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones.
