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, everyone in our group had different results, one person had more DNA than the others. It is the case because everyone had different amounts of cells left in their cheeks. The amount is affected day to day because if you have braces you could scrape more off than if you didn't.

= DNA Replication = DNA replication is a process in which DNA is replicated so it can be passed on to your children. It starts out when the helicase breaks DNA apart by splitting the hydrogen bonds. Once the strands are broken apart they must stay apart somehow. That is where the single stranded binding proteins come into action. Their job is to make sure that the strands stay apart for good. The next step is to attach a primase. A primase gives a starting point for this process. DNA replication always starts at the 3’ end. The final step is to attach a polymerase. The process starts on the leading strand. It starts at the 3’ end and goes towards the replication fork. From there it goes to the lagging strand. It starts at the 3’ end, in the replication fork, and goes in the opposite direction. In the lagging strand the short replicated strands are called Okazaki fragments, the ligase fills in any gaps between each fragment.
