Suppose you fill up a beaker with 1 mole of isolated HIV. What would be the consistency of this collection of HIV? Slimy? Liquid? What color would it have? If you would put your finger in it, would it infect you if you have no open wounds on your finger, i.o.w. does it penetrate through your finger skin? Are all viruses of a certain species totally identical (considering no artificial manipulation and no mutation)?
