flat =Cheek Lab 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?

Nobody in our group had the exact same extraction results because everybody has different DNA and for other various reasons affecting your cheeks. The amount of DNA that we extracted affects our day to day activities because whether you have raw cheeks from biting them, you were chewing gum, or perhaps you have braces it all depends. These variables make the difference because when you do the experiment it can affect your outcome.

=Replication Summary: = Adenine and Guanine are purine’s, which means they have two rings. Thymine and Cytosine are pyrimidine’s, which means they have one ring. The purpose of DNA replication is to be able to make offspring and regenerate new cells. You need to know this before you start the replication of DNA. The first step in the replication process is to break hydrogen bonds using Helicase. Helicase is an enzyme that breaks apart DNA. Next, single stranded binding protein attaches to keep the strand from coming together. Then Primase can attach to give a starting point for the process. Polymerase is an enzyme that binds to the DNA and begins to replicate. Then the lagging strand replicates. Fragments of DNA on the lagging strand are called Okazaki strands. The lagging strand needs to replicate in fragments because it replicates in a different direction than the leading strand. The lagging strand is called this because it follows behind the leading strand. This process ends with ligase binding Okazaki fragments together.
