DNA Animal Cell Conclusion

It was hypothesized that if the procedures were followed through correctly strands of DNA would be visible in the sports drink. Observations of this experiment included that as the sports drink was spat back into the cup and poured into the test tube, it was noticed that the color or the sports drink was less blue, and particles were visible throughout the liquid. As the lysis was added, the amount of the liquid in the test tube increased to 9mL from 7mL. As the tube was incubating in the beaker for fifteen minutes no differences were really taken note of. It has been considered that the DNA strands were not visible, because the test tube was taken out of the beaker more than it should have been. Possibly the lysis and the sports drink had not been combined exactly right. The reliability of this experiment is not the greatest, because some directions on the procedures may have been mistaken by the experimenter. However if procedures are followed carefully, the lab shows a pretty good reliability. This experiment was controlled by the fact that everyone had the same sports drink, the same amount, and the same amount of lysis. The cups and test tubes were all the same throughout. From this lab, it was learned that lab procedures must be followed precisely. However by observing another's DNA experiment, it was also shown how DNA strands from our cells appear.
