A PhD student has been given a tissue sample that looks like gut epithelium. How might the student go about gathering further evidence to support this experimentally?
A) Test the DNA of the tissue for molecular markers that correspond to epithelium
B) Measure the cytoplasmic content of the tissue, the concentration of which proportional to the tissue volume is indicative of cell type
C) Determine if the tissue is absorptive and secretes enzymes
D) Extract total protein and run on a 2-D gel matrix
E) All options listed here are correct
