Unit 5 Reflection

This unit talked A LOT about DNA, and how it is formed, copied, and wrapped several times, to make chromosomes. In the past couple of weeks, I have learned really how great our DNA is. Did you know that our DNA can copy 100 trillion times in a second? Just yesterday we learned about Protein Synthesis. Protein synthesis is a series of chemical reactions in which molecules are brought into contact with one another and chemical bonds are formed and broken. Even before that. We also learned a lot about mutations. In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. We learned that in a DNA sequence, one slip up, and you end up with a mutation for life. Over the course of the past few weeks, I really learned how precise biology is and how detailed it is.
