Experiment 3 Post-Lab Questions 1. What color are the Gram-positive bacteria after Gram staining? Gram-negative bacteria? (5 points) Gram-positive bacteria appear as dark purple or blue due to retaining the primary dye (Crystal Violet) in the cell wall. Gram-negative bacteria appear as red or pink due to decolorizing to accept the counterstain (Safranin). 2. What […]

Pre-Lab Questions 1. What determines if a bacterial cell is Gram-positive or Gram-negative? (5 points) Amount and location of the peptidoglycan molecule in the prokaryotic cell wall determines whether a bacterial cell is Gram-positive or Gram-negative.   2. In this lab, both viruses and prions were introduced as acellular organisms. Do some research and describe
