Nucleosomes are the basic unit of DNA packaging in eukaryotes, consisting of a segment of DNA wound around a histone protein core while nucleoid (meaning nucleus-like) is an irregularly-shaped region within the cell of a prokaryote that contains all or most of the genetic material.
The parts of the nucleus reflect its functions. Most of the time, the entire nucleus is separated from the rest of the cell by a double-layered nuclear envelope. This membrane is covered with pores that regulate the movement of molecules in and out of the nucleus. Inside the nucleus, the nucleolus produces ribosomes, which make proteins for the cell.
