Unit five was about DNA and RNA, DNA replication, and mutations. DNA replicates by separating the two strands. First, the DNA unzips, then it matches the the nucleotides, and finally the result gives you two identical DNA strands. DNA is made from a double helix, which are two strands connected by adenine, thymine, guanine, and cytosine. To make a proteins, DNA goes to RNA, then it becomes a protein. The process where DNA becomes RNA is called transcription, when RNA becomes a protein it is called translation. The result is a long chain of amino acids. Mutations can be good, bad, or not affect anything at all. Insertion, deletion, and frameshift all can change the code of DNA.
My weaknesses were understanding the process of protein synthesis, while mutations were a bit confusing. The gene expression and regulation vodcast was a bit confusing. From this unit, I learned about DNA, how to extract DNA, mutations, and what DNA does for someone. I want to learn more about how your cell does this. I wonder how DNA is programmed to automatically do all of this.
