You are setting up an experiment to stain cells with DAPI (4',6-diamidino-2- phenylindole). Your stock solution of DAPI is 1 mg/mL. You need your final staining solution to be 1 ug/mL. a) What is the dilution factor you need to use to go from your stock solution (1 mg/mL) to your final staining solution (1 ug/mL)? you can. Show your workings if . b) To what regions of DNA does DAPI bind? Describe in terms of the bases and part of the DNA double helix. c) You notice multiple especially dark speckles in the nuclei of your cells when you look under a microscope. What kind of DNA/chromatin do you think this is? Think in terms of more or less actively transcribed DNA regions.
