Gel loading dye contains different components such as tracking dyes (bromophenol blue, xylene cyanol), glycerol, and buffers which can give different coloration to DNA samples due to their chemical properties and interactions. The color differences help visualize the DNA movement in the gel during electrophoresis and also indicate the loading efficiency.

Take the actual sample weight of 13grams, and divide it by the atomic weight of chromium. This gives you your molar percentage of atoms. Now multiply this molar percentage by Avogadro's constant, the number of atoms in one mole, and this will give you your number of atoms in the sample.
Could a water sample have a high concentration of the pathogenic bacterium vibrio cholerae and give negative results in the multiple-tube technique?
Yes, a water sample could have a high concentration of Vibrio cholerae but give negative results in the multiple-tube technique if the bacteria are unevenly distributed in the sample. The technique relies on statistical probability and multiple dilutions to estimate bacterial concentrations, so if the samples taken from the dilution series do not contain the bacteria, the results can be falsely negative.
