At the beginning of class Mr. Finley chacked if we had done the homework. He then talked about how we should read over things multiple times to make sure we get what we are reading. He said we can also write things down and use the pictures provided to help you understand. We continued the notes that we had started on Thursday. We learned all about DNA and how only some kinds go together. Adenine and Thymine go together and Cytosine and Guanine go together. Then we moved on to how DNA replicates. We said that the parts of DNA seperate and other parts of DNA that are floating in the nucleus attach to the parts that seperated. That replicates it and makes more DNA. 50% of the DNA is new and 50% of it is old. It is called semiconservative because it saves half of the old DNA.
