Cheek DNA lab

Homework Question ( complete individually and turn in on your individual wiki page - be sure to use complete sentences ) -( 6 points)
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?

For this lab, not everyone in our group had the same extraction results. I had more than Morgan. This could be the case because I could have bit my cheek more that she did. The amount of DNA that you extracted affects your day to day activities because of what each of us had for lunch, what cheek cells were loose, or even our genetic DNA cells.

DNA Replication Summary


The DNA replication process is important because DNA is used in reproduction to pass genes. First, the enzyme Helicase must bind the DNA strand and break apart the hydrogen bond. This will create a replication fork. This step is important because the double helix strand is all connected. After the Helicase enzyme splits it, the DNA strands are able to be replicated. Second, the single stranded binding proteins attach and keeps strands from coming back together, so there is a separate leading strand and a separate lagging strand. This one step is important because it will not allow the two strands to join together. The replication process would not be able to continue if the leading strand and the lagging strand came back together before it was started. The next step starts on the leading strand. The enzyme, primase, gives a starting point to replicate DNA. This enzyme is like the starting gun before a race. If it did not occur, the other steps would not know when to happen. The primase attaches to the leading strand, which is the top strand. Next, the polymerase binds and replicates DNA. The okazaki fragments are used by the lagging strand. The enzyme, ligase, pins the okazaki fragments and fuses them together. The lagging strand requires the Okazaki fragments because the strand has to wait for the DNA to unravel.
