yeah.. First half of class today was discussing grade reports of quarter 2 of this semester, which covered over the Unit 3 Exams (all of which Mr. P managed to grade!) and any other included grade factors such as the Postcard Project that was turned in yesterday. Today we were also assigned the Tribune Article Project, due on 11/23/10.
After this talk of grading, we moved on to a presentation on Genetics and DNA. It was explained how DNA can be utilized to find the genetic characterstics of living things, and with this comes some issues of knowing about specific diseases existant in one's body without them knowing, and some matters over the use of it in Forensics and tracing DNA back to find information, ect. There also comes some major debate over humans' "messing around" with the natural way of genetics by the means of cloning and genetically breeding living things, especially when it comes to crops and livestock in the food we eat, and even other humans.
In Memory of Dolly (1996-2003)
Now, just make sure to keep in mind that all the information below is what was presented in class and I recorded into the packet we were all given to contain these notes (STS Biology - Genetics I - Student Notes). Also be sure to check out the Texter for stuff.
In 1953, American and English molecular biologists James Watson and Francis Crick researched into discovering that the structure of DNA resembled a helix/spiral/ladder-like strand that has come to resemble this form we are all familiar with today:
DNA, or Deoxyribonucleic Acid, has 3 significant structural components:
- Deoxyribose - 5 Carbon sugar
- Phosphate Groups - PO4
- Nitrogen Gasses - Connected by hydrogen bonds
- Nucleotide - Sugar, Phosphate, and base as one unit
- Polymer - Multiple units
- Double Helix - 2 strands connected by hydrogen bond
Going deeper into the DNA structure, and its nitrogen bases: 
- Purines - Adenine (A), Guanine (G)
- Pyrimidines - Thymine (T), Cytosine (C)
Well then, this was all that was covered in the first page of these notes in-class, and we will continue to get this down in the next few days. Remember, pages 7-8 in the UP must be filled out, and it can help you comprehend this.
Again, sorry but I don't know you guys well enough to put down a next scriber, so it will be announced. Our next class is actually Friday, but hey, come to school tomorrow morning anyway. You're just that cool... Have good Veteran's Day, and bless our servicemen and women!
