A Blast From The Past: When Michelle Became Interested In The Medical Field

 Michelle has been learning about DNA. Here she will show you some of what she has learned.

                                                                 

                                         Build A DNA Ladder                                      



You use four different colored tubes to build this model of DNA. Green is for Adenine, Red is forThymine, Blue is for Guanine, and Yellow is for Cytosine. To build the ladder you must follow these rules: Green can only pair with Red T. Blue can only pair with Yellow C.

                                    


A Double Helix
This is a shape of the DNA molecule. 
You should make a complete twist every 10 base pairs.


                                                         

                                                 Unzip The DNA Ladder

 Pull apart the DNA ladder. Put one half of the DNA ladder on the left, put the other half on the right


Remember: A always pairs with and always pairs with G.
You have now learned the secret of DNA Replication.

  1. DNA is so fascinating, isn't it? She might enjoy the DNA extraction from strawberries we did recently.
