=DNA Homework=

Did everyone in your group have about the same extraction results? Why is this the case? How is the amount of DNA that you extracted affected by your day to day activities?

No not everyone had the same amount of DNA extracted because everyone is different and some people chew on the cheek and that will loosen and loose the DNA. The amount of DNA that was extracted means that may lose some abilitys in your body.

=DNA replication Summary =

DNA has the bases Guanine, Cytosine, Adenine, and Thymine the DNA. Guanine and Cytosine always go together and Adenine and Thymine always go together. To begin the replication, the DNA has to spit up into two different strands and those strands are the leading strand and the lagging strand. There is a difference between the leading strand and the lagging strand. The fragments on the lagging strand are called Okazaki fragments. The leading strand will always go first and then the lagging will follow. You have the primase and polymerase again. Then you also have ligase, which it brings the fragments together. Then these proteins called single stranded binding proteins attach to keep all of the strands from coming together. An enzyme called primase is the starting point. Then an enzyme called polymerase binds and begins to replicate the DNA.
