Period 8 November 10 Scribepost

We started the day with the following:


Announcements:
          Mr. Paek told us our homework, passed out our progress reports which had our test grades, passed out a new packet and calander for the month and told us about an assignement that is due November 23rd. The assignement is in the new packet "It's In Your DNA!" on page 3. He also showed us examples of papers that have been already completed. All in all the assingement is a paper about how you discovered the way DNA looks like(double helix). Ask Mr. Paek for more info. :)

Homework:
          Like I said before the homework is the assignement that is due on November 23 and the other homework is in the new packet "It's In Your DNA!" on page 7 and 8 that are due friday.

In Class:
          Mr.Paek made a power point and handed out another fill in the blank packet ( STS Biology Genetics I Student Notes) to the slide show so we can make notes on it.

This is how many notes we took so far:

Researchers involved in the Discovery of DNA

Watson and Crick won the Nobel Prize for discovering structure of DNA in 1953 however Rosalind Franklin helped with the discovery but she died an an anonymous person because Watson and Crick took all of the credit.

Model of DNA



                                                                         





DNA Structure: deoxyribonucleic acid.
1. Deoxyribose- 5 carbon sugar.
2. Phosphate group- PO4.
3. Nitrogen bases-connected together by H bonds.

Nucleotide: are the single units that make up nucleic acids

Double Helix- 2 strands connected together by a nitrogen bond.

Types of Bases: Purines and Pyrimidines.

Purines: Adenine (A), Guanine (G)

Pyrimidines: Thymine (T), Cytosine (C)

                                           -And thats all the notes we took.


         Our class also had a discussion about cloning: how it is illegal, what we know about it, any movies with cloning in it, and what our opinions are on it. We also discussed stem cell research. We debated on if it is okay to do so or just plain bad. Did you know that the embryo already has a heart beat by the time of 6 weeks? And at the end we had about three minutes to work on our homework: pages 7 and 8 in the new packet.


                                     Clones :) ( so cute )




                    Stem Cell Research

Thats all for today :)
