flat =Cheek Cell Lab= The results for our cheek cell lab weren’t the same for everyone. Jensen had way more DNA strands than anyone else. Things such as what you ate for breakfast, how hard your scraped your cheek, if you have braces or not, and how you did the procedure could all effect the results of this lab. The DNA that you extracted is affected by your day-to-day activities by doing such things as drinking a lot, eating before testing, chewing gum, brushing your teeth, and having braces or a retainer that gets in the way. All of these activities affect how much DNA was extracted in this lab.

= Replication Summary =



flat =Replication Model =


 * Telomeres are the long stretches at the end of chromosomes that protect it and keep it from attaching to other chromosomes. Polymerase can only start replication on a 3’ end. When the replication fork opens the Polymerase can make an Okazaki Fragment, which is a small part of DNA that helps to unzip the replication fork. After, DNA ligase fills in the gaps in between Okazaki Fragments to replicate DNA. Telomerase is an enzyme (ribonucleoprotein) that adds sequences of telomeres to the 3’ end of DNA. By doing this, the polymerase is able to complete the replication. A feature that shows a caner cell different than a normal one is its ability to grow. 90% of cancer cells divide uncontrollably to cause the tumor to grow. Patients get rid of bad cells and get them transformed with the gene that they have been unable to receive. If cells could be transformed with an active telomerase and therapeutic gene it could give it a whole life span. When being cloned, or given parts of a cell from another cell, that isn’t your own, your telomeres are shorter than normal length. Also, it depends how long the cells that you are getting were in the organism before. If they are younger, your telomeres could be almost to normal size. Cellular Aging leads to the shrinking of cells. After every mitosis it grows out the cell and makes it shrink. **
