"It's In Your DNA!" NEW UNIT!

Today in class we started off by handing in our 12.2 notes. Then we got a current grade report which had our test score on it. After, we took a look at them, Mrs. Stein explained out Tribune Article assignment. It is located in the UP packet pages 3-4. The purpose of the assignment is to pretend we invented the structure of DNA and write a newspaper article on hoe it all happened. After she was done explaining, we started our new unit on DNA. We got into a group of 3-4 people and discussed by writing a paragraph with 7 words. They were nucleotide, nitrogen base, DNA, double-helix, phosphate, structure, and genes. My groups went something like this:

-DNA is genetic material that transfers genes and is in a cell. The structure of DNA strands is a double-helix discovered by Watson and Crick. DNA consists of nucleotides which are adenine, thymine, guanine, and cytosine. They are held together by phosphate groups and nitrogen bars.

We then picked up two pictures that looked like this:
                                    

-Then using those pictures, we went into talking about the basic structure of DNA.
  

Notes we took in class:
     -DNA stands for Deoxyribonucleic Acid.
     -Nucleotides are subunits of DNA.
           *All nucleotides have a:
               -Nitrogen Base
               -Phosphate group
               -Sugar (deoxyribose)

     -Types of Bases:                                      
           *Purines
               -Guanine      
           *Pyrimidines                        
               -Thymine
               -Cytosine

     -Order of Nitrogen Bases: Give instructions for making protein.

     -Base Pairing:
           *A pairs with T
           *G pairs with D
           *Bond using hydrogen bonds
           *Back-bone is made of deoxyribose phosphate.

We finished off class by watching a Bill Nye Video, as a recap of all the things we had just talked about!
