In one experiment, you coat a petri dish with fibronectin and proteoglycan and culture cells on a petri dish. Cells adhere to the dish. In another set of experiments (Experiments 1-4), you repeat the previous procedure but this time add one synthetic peptide to each of the culture dishes as the cells are added. What are the outcomes of experiments 1 to 4?  Experiment 1: TGKGDAPC Experiment 2: TGRGDPSC  Experiment 3: RVDSPAC Experiment 4: RGDSPAC
