When it comes to being sick or having a disease, do you know if you have a bacterial or viral infection? many people don't know there is a difference. for this project, let's see if you are aware of the many differences between bacteria and viruses. test your knowledge in the activity below!

Asingle-molecule microscopy experiment is performed on a slide containing 1000 molecules each of green, red, cyan, and yellow fluorescent proteins (gfp, rfp, cfp, and yfp, respectively). the experiment measures the number of antibodies bound to each type of protein, finding that 900 molecules of gfp, 10 of rfp, 1 of cfp, and 3 of yfp are bound at 1 nm concentration of antibody. a. what is the specificity of the antibody for gfp? b. what is the kd of the gfp–antibody interaction?
