Genetics Post 2

Even though I have done genetics I never knew a lot of these facts. I learned a hoard of new things that I never knew! One thing I learned was that chimps and humans ( on the genetic level) are almost exactly alike except for a few minor differences in DNA. Another important thing I learned was that there isn't a relationship between the number or chromosomes and the number of genes. From the second link I learned that our chromosomes are not one big strand because our bodies are so complex and because we have a tremendous amount of DNA in our bodies. Other organisms like bacteria keep all their DNA in one strand. They do this because they reproduce asexually meaning when they reproduce each bacteria gets half the copy of the same DNA. In the third link I found something out that added on to this concept. We have an enormous genome compared to those bacteria. Since our genome is so big we divide it all up into our 46 chromosomes. After reading the links I was really shocked. It taught me so much!
