Homework tonight is pages 201-205. Parts 1-3 of the Punnett square packet are due tomorrow (Tuesday), Parts 4 and 5 are due Wednesday, and the entire packet is due Thursday.
Today we discussed how a majority of traits are controlled. Very few traits are controlled by Mendel's pattern of inheritance. Those that are not are called "non-Mendelian genetics". Examples are incomplete dominance, co-dominance, multiple alleles, polygenic traits, and sex-linked traits.

Today we discussed the importance of Gregor Mendel and his contribution to the field of genetics. We also began Punnett squares and how they can be used to predict outcomes of genetic crosses. Homework this weekend is pages 207-216, 219.
Punnett squares were also assigned. Parts 1-3 are due by Tuesday. More protein synthesis today! Today we are mutating a hypothetical gene in an action figure/stuffed animal. The document needed for instructions is in the documents folder. Remaining time is used to review. Mutations notes can be found in the notes folder.
Today we practiced the process of protein synthesis by examining short segments of DNA for some interesting, real-life proteins. The handout that was used in class can be found in the documents folder and the protein profiles can be found in the classroom, below, and HERE as well. Today we discussed protein synthesis. Please access the powerpoint for help, more information, or if you were absent. You can also watch the video below. Realize, some parts of this video go into more detail than we do in preAP, but it's a great resource. The second video is from the Ameoba sisters. It's a little cheesy, and a little annoying, but it is educational. ;) Today, we finished our discussion on how organisms create gametes, or sex cells, for sexual reproduction. Information can be found in the "Meiosis" powerpoint.
We then had a lab where we observed mitosis in Allium (onion) root tips. The file to be used is in the labs folder, in a folder called "Observing Mitosis Lab". Since absent students will lack the capacity to observe actual Allium cells, an online version that is similar can be found HERE. Students should still use the sheet provided and answer all pertinent questions, but use the virtual lab instead of microscopes and slides. If a student still wishes to do the full lab, they can speak with me to set up a time before or after school. We reviewed the cell cycle today and finished watching the documentary from yesterday. A class discussion followed.
We then began talking about meiosis and how organisms create gametes, or sex cells, for sexual reproduction. We discussed the importance of cell cycle regulation and what happens when it goes awry today. Information can be found in the Cell Cycle powerpoint. We then watched "Dear 16 year old Me" and the documentary "Vice: Killing Cancer". Homework tonight is pages 181-186. Today we discussed how the cell divides, or mitosis. We learned the steps and did a quick practice afterwards. Information can be found in the Cell Cycle powerpoint.
Homework tonight is pages 153-155. Today we discussed the copying, or replication, of DNA and why we need to make copies in the first place. The notes can be found within the powerpoint entitled "DNA Structure and Replication".
We then extracted DNA from strawberries to observe what a giant cluster of DNA would look like. Turns out, it's snot. The optional project, building a DNA model, was assigned today. Directions can be found in the "Documents" folder in Unit 3. |
