5.1 Summary of findings
UV rays do have a negative effect on UV-sensitive yeast cells and they hinder their growth.
5.2 Practical Applications
A practical application includes educating bakers the effects of UV rays on UV-sensitive yeast. As such, they would be more cautious in choosing the correct type of yeast when baking. After knowing of the negative effects UV rays can cause onto yeast cells, they can be more careful about exposing the yeast to UV rays which may affect the final product produced or even cause disastrous effects on the consumers.
Another application includes using yeast as a perfect model for researching because of the overlapping genes in yeasts and humans. For example, yeast genes can be removed and replaced with human genes to test drugs and mutagens. Yeast genes resemble human genes and our DNA is very similar that in some areas, a human gene can be swapped out for the equivalent yeast gene. Because of this, researchers can do research work and yeast and test in on yeast cells on topics related to humans. In the long run, this saves time because human cells take about 24 hours to duplicate while yeast cells take only about 2 hours.
Lastly, since it is proven that UV rays do cause negative effects on yeast cells, and yeast cells and human cells share several similarities, UV rays probably can cause harm to human cells too. Thus, this serves as a warning for people to take precaution whenever they are outdoors, like applying sunblock or staying under the shade.
5.3 Areas for further study
Further studies can be made to find out what other factors affect the DNA or growth of UV-sensitive yeast. There might be other factors other than UV rays which affect UV-sensitive yeast cells and studying them can really improve our experiment. Several other types of yeasts can also be used in the experiment other than UV-sensitive ones, to find out how different types of yeast respond differently to UV rays.
