Answer #1

blood contains 45% Red blood cells and these cells are highly specialized in carrying oxygen from lungs to all over tissues in the body. for these all organelles are removed and hemoglobin is present in the cells mainly. globin is a protein in complex with iron. when the protein is having natural structure in blood plasma and other it can complex with iron. but as soon as it get dry then it globin protein denature and looses it 3D complexing structure and releasing free iron and upon oxidation iron oxide is black brown colored insoluble stain.

Lab 9 – Molecular Biology In this lab, you will prepare an agarose gel and use gel electrophoresis to compare the size of 2 dye molecules Methyl orange and Ponceau G. You will also analyze an “unknown” sample that contains a mixture of two dyes. Dye molecules with lower molecular weight or greater electrical charge will migrate faster through the gel, than dye molecules with greater molecular weights or lesser electrical charge. Materials: Mini gel electrophoresis chamber 6 Tooth comb...
