WebSep 4, 2014 · The nucleus is a large organelle that contains the cell’s genetic information. Most cells have only one nucleus, but some have more than one, and others—like mature red blood cells—don’t have one at all. Within the nucleus is a spherical body known as the nucleolus, which contains clusters of protein, DNA, and RNA. WebCell, or Plasma, membrane - encloses every human cell. Structure - 2 primary building blocks include protein (about 60% of the membrane) and lipid, or fat (about 40% of the membrane). The primary lipid is called phospholipid , and molecules of phospholipid form a 'phospholipid bilayer' (two layers of phospholipid molecules).
