Today in bio class we turned in the homework from the previous night- pgs, 7-14 in our UP and Mrs. Stein reviewed with us what we had learned. Basically, what makes up a nucleotide? Phosphate, a nitrogen base, and deoxyribose (sugar) and what connects nucleotides? Hydrogen bases. We took a quiz on on section 12.3 and then took MORE notes on DNA replication. We learned about histones, which are proteins which DNA is wrapped around and that DNA replicates in the S phase of interphase. We also learned that DNA replication results in two indentical DNA strands. Finally, we learned about Semi-Conservative Replication, which is when each new molecule contains one old strand and one new strand.
Then, we watched an animation about DNA Replication and a movie about the Human Genome Preject. The HGP is a bunch of scientists that are striving to map out all the genes in the human body and where they are located. They are practically finished.
