flat =About Me= My name is Marissa, I'm a freshman in high school. I run track and cross country. I like to listen to music and hang out with friends. My favorite band is My Chemical Romance.

=Big tooth Aspen= The Big tooth Aspen also know as //Populus grandidentata// is a deciduous tree. This scientific name refers to the leave's course teeth. The Big tooth Aspen is simple, its leaves are alternate and have a dentate margin. Its seeds are covered in long silky hairs; the leaves also have large course teeth. When the leaves are young they are whitish and wooly underneath. The Big tooth Aspen is related to the Quaking Aspen and the Paper Birch because of the way the flutter in the wind. The wood from the Big tooth Aspen is used for making paper. http://en.wikipedia.org/wiki/File:Populus_grandidentata.JPG

=Red bud= The Red bud tree also know as //Cercis canadensis// is a tree know for its flowers that are light to dark magenta in color. These flowers appear from March to May. The Red bud is a deciduous tree. Its leaves are heart-shaped, simple, alternate, and have an entire margin. The Red bud has course grained wood. The Red bud is related to the Black Locust. Red buds are often planted as ornamental trees. Native Americans would consume the flowers raw or boiled.

I found that simple sugars are absent, proteins were present, starches were present, and fats and oils were present. Another food that my group tested was peas. Peas tested negative for simple sugar, starches, fat and protein. In vegetables the presence of simple sugar was absent, starches were present except in lettuce, fat was also absent, and protein is present in the cannellini bean and potato. Protein was absent in the lettuce. According to the class results peas tested negative for protein. In fruits the simple sugars were present. Starches were present in the banana and the avocado. Starches were not present in the apple. Fats were present in the apple and avocado. The results for the banana were half and half. Protein was present in the avocado and the apple according to the results. The results for the banana were half and half. In the meats simple sugars were absent. Starches are absent in ground beef, but in liver the results were half and half. Fats are present in the meats. Protein is also present. In the dairy products, simple sugars are not present. Starches were present in the egg yolk, but not the egg white or milk. Fat was present in milk and in egg yolk, but not in egg white. Protein was present in each of the dairy products. I was surprised to see that there were starches in the banana. I had always believed starches were in vegetables such as potatoes. I was also surprised that fat and protein was present in the apple. I had believed fat could not be found in fruits, and protein was only present in things like meats, eggs, and nuts. I expected to find starch in the egg white since there was starch in the egg yolk. Vegetables should have tested positive for simple sugars except for lettuce. The apple also tested negatively for starch but does actually have starches. Peas tested negatively for protein but do contain protein. =Biomolecules Infographic=

=Cheek Cell Lab Homework Question=

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? – **Everyone did not have the same results because there are many factors that could case a person to give more or less cheek cells. Some of these include, chewing gum, and having braces. If you had been chewing gum the cheek cells that would have naturally fallen off would have been incorporated into the gum. If you have braces the wires easily scratch your cheeks which would cause more cheek cells to shed. In my group, Janell had the best results because she has braces. The amount of DNA that is extracted is affected by day to day activities because if you had just brushed your teeth there would be less cheek cells to collect because most of them would have been brushed away. Eating a meal could also cause more cheek cells to shed.**

= DNA Replication Summary =

DNA replication is a process that has four steps. Adenine and Guanine are purines, which, means they have two rings. Thymine and Cytosine are pyrimidines, which means they only have one ring. These are what make up the strands of DNA. The first step in DNA replication is to break the hydrogen bonds between the two strands using the enzyme helicase. In the next step single stranded binding proteins attach to keep the strands from forming back together. The two broken strands of the DNA are called the leading and lagging strands. We start with the leading strand. The enzyme primase creates a starting point for replication to begin. The enzyme polymerse then begins the actual replicating of the DNA. For the lagging strand the steps are the same as the lead strand with one difference. Primase and polymerse form different fragments along the strand called Okasaki fragments. These are then bound together by the enzyme Ligase.
