Yоu аre given fоur test tubes, numbered 1-4, thаt cоntаin purified macromolecules. One test tube contains hemoglobin (a protein), one contains cholesterol (a lipid), one contains starch (a carbohydrate), and one contains DNA (a nucleic acid). Use the information below to determine the identities of the macromolecules present in each of the four tubes. Test tubes #2 and #4 contain nitrogen, but the other tubes do not The contents of test tube #3 are not soluble in water, but the contents of all other test tubes are water-soluble. The contents of test tube #1 can be broken down into monomers that are all exactly identical to each other. The macromolecule in test tube #2 has quaternary structure. Tube 1: [Tube1] Tube 2: [Tube2] Tube 3: [Tube3] Tube 4: [Tube4]
