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.
It is not surrounded by a membrane but sits in the nucleus. The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes.Ribosomes make proteins; therefore, the nucleolus plays a vital role in making proteins in the cell.unction of the Nucleolus. Ribosomes are made of two subunits, a large and a small. Each subunit is manufactured separately in the nucleolus. The proteins needed to make them enter the nucleus through pores in the nuclear membrane. The rRNA is made in the nucleolus itself.
