1. What is the purpose of using salt? 1The purpose of using salt is to help DNA stick together, so that we see clumps of tangled DNA molecules. 2. What is the purpose of using the blender? 1The blender separates the cells (of the onion or liver) from each other, so that there is a really thin soup-like liquid of cells. 3. What happens when you add the soap? 1When soap is added it breaks through the cell membrane and the nucleus. 4. What is the purpose of the alcohol? Why does DNA rise to the top? 1In water DNA normally stays dissolved but when alcohol comes in contact with salty DNA it becomes undissolved, creating a precipitation. DNA rises to the top because the alcohol that was added is less dense than the water or cell scum (which

Acheta Lab Report
876 Words | 4 PagesThe general pattern was thus: all DNA samples remained intact for all salt concentrations at 25˚C, 42˚C, and 65˚C, as the sample delta brightness was within one standard deviation of or significantly brighter than the average control brightness value; this indicates that the treated DNA was not degraded from its previous genomic state by the applied treatments. All samples were also to various degrees destroyed at 95˚C, as the delta brightness was very low and thus experimentally obtained brightness results differed little from the background luminosity. Judging by a strictly qualitative analysis, replacing the Cl - ion bonded with Mg 2 + with SO4 2- had a minimal effect on DNA quality because of both molecules ' negative charges that are repelled by similar negative charges in the DNA backbone, but it is evident that magnesium sulfate preserves slightly more of the 10kb DNA sample than does magnesium chloride at 95˚C, as is evident when comparing the last 3 lanes of the bottom rows on gels displayed in Figures 1 and 2. Ammonium sulfate, rather than displaying the banded pattern of magnesium sulfate, exhibits an even smearing pattern, as evidenced by the same bottom lanes in Figure 3; however such information cannot be deduced from the values obtained by
