1) You are studying the toxic protein called ectatomin, a major component of ant venom (specifically from the species Ectatomma tuberculatum), that embeds into cell membranes and creates pores that cause cells to lyse. Ectatomin is a small dimer, meaning the protein is comprised of two polypeptides; the sequences of the two polypeptides are given in the table with single-letter abbreviations. polypeptide sequences of ectatomin monomers polypeptide |protein sequence polypeptide 1 GVIPKKIWETVCPTVEPWAKKCSGDIATYIKRECGKL polypeptide 2 WSTIVKLTICPTLKSMAKKCEGSIATMIKKKCDK You could use absorbance at 280nm or colorimetric assays like the Bradford assay or bicinchoninic acid assay (BCA) assay to quantify the amount of ectatomin you have for your experiment. Why might you choose to use a colorimetric method instead of absorbance at 280nm? Select the best answer. a) Measuring absorbance at higher wavelengths, like 595nm or 562nm, is more accurate than measuring absorbance at 280nm. b) The Bradford…
