5) In an SDS PAGE electrophoresis analysis of protein molecular mass, If standard proteins X (Mw 20,000 ) and Y(Mw45,000) move 3.80cm and 1.55cm, respectively, on the same gel. Estimate Mw of the unknown protein Z which move 2.45cm on the same gel, under the same condition. 6) Estimate the contour length and root mean square separation of a polycarpolactone (structure shown below) with a molar mass of 120,000g/mol 7) The graph below showed light absorption spectra (using a spectrophotometer) of malachite green, a common industrial dye, at different concentration (ppm, parts per million, by weight) in water. The numbers indicated on the graph are concentrations of the dye used in each scan. Malachite green destroys fish eggs in natural water sources and causes liver cancer in human
