You should describe where in the cell the structure is located and the function of the structure. If you are reporting on a protein or toxin, be sure to talk about the specific function of the protein and how it may contribute to disease.
If there is an equivalent structure in eukaryotic cells, explain to us if they are the same or how they differ.
Find a website that shows us a diagram of the structure you have chosen. (Provide an active LINK and brief description of the image)
