Introduction to Genetics and Cell Biology was my most challenging biology class so far. There are so many different parts under the genetics category and there is a lot of overlap, so it is hard keeping everything straight. Genetics is an interesting subject because that is what makes everybody different. I think it would be awesome to do some research in that field, so that is why I will be taking Genetics next semester. I’d really be interested in working with modifying DNA that has mutations or something along that line, but I haven’t looked enough into it to know what I can actually do. I had consistent B’s on the test until I got a high C on the last one. I did really well on all the other assignments and before I took the final exam, I had an A- and I needed a really high grade on the final to keep it, but I ended up getting a B+. I was determined to get an A but I fell short. I gave it my best shot so that is all I can ask for. I really enjoyed the lab for this class.

Here is the poster that my lab partner and I made for Research Day. For the lab, we got to choose where we could grow yeast from samples that are prone to having yeast. We took water samples from Briery Creek Lake and Wilkes Lake. The yeast from each sample was grown and isolated. Then morphological, biochemical, and genetic tests were ran on the samples. It was determined that since there are different selection pressures on each lake the yeast was morphologically, biochemically, and genetically different.
