Today's class got interesting toward the end, but let's start with the beginning. We turned in Unit Packet pages 7-14. There were there little picture handouts to pick up as you came in. Homework from the weekend was read 12.3. So to make sure we read it, we took a mini quiz reviewing info covered. Next, we labeled the pictures:
A Simple Pic of DNA Replication
<---- 1. Parent DNA 2. H bond breaks, "unzipping" the DNA 3. New DNA strands form with help from DNA polymerase 4. Two new DNA molecules
A More Detailed Pic of DNA Replication
<---- 1. New Strand 2. Replication Fork 3. DNA polymerase 4. Original Strand 5. Nitrogen Bases
A DNA Molecule Up Close ^^^^^
1. Chromosome 2. Nucleosome 3. Coils
4. Supercoils 5. Histones 6. DNA
Then, we took some notes:
DNA replicates during S-phase of interphase
>2 copies needed for mitosis
4. Supercoils 5. Histones 6. DNA
Then, we took some notes:
DNA replicates during S-phase of interphase
>2 copies needed for mitosis
Semi-conservative replication
>each new molecule contains one old strand and one new strand
The remainder of class was where it got interesting because we talked about...CLONING! We talked about how people are trying to clone a woolly mammoth, animals, and humans and why? We were going to watch a movie about the Human Genome but we didn't have time so we will watch it tomorrow. Mrs. Stein said she only had about 5 cancer papers left to grade and we might get them back tomorrow! FIN
Homework:
>Tribune Article due 11/23
>Read 13.1 with Double Bubble Map "DNA vs. RNA" due tomorrow
>Read 13.1 with Flow Map "Protein Synthesis" due Wednesday
The next scribe will be Andrew
