=flat= About me I am a freshman at PHS. I play baseball, basketball, and football for the school. My favorite subject in school is science. I have a dog named Abraham. In my spare time I like to hang out with my friends.

=Flowering Dogwood= The name of my tree is Flowering Dogwood. The scientific name is __//Cornus florida//__. Some other trees the Flowering Dogwood is related to is the Progada Dogwood, and the Giant Dogwood. The Flowering Dogwood is deciduous, also it is simple, and it has opposite leaves, and the leaves are rounded. Some characteristics of the tree are a red-brown to reddish gray bark, the leaves turn bright red in autumn, and it is a small native tree with a low spreading crown. The Flowering Dogwood is primarily used for textile weaving shuttles. http://en.wikipedia.org/wiki/Flowering_Dogwood

=Larch= The name of my tree is the larch. The scientific name is __//Larix laricina//__. Some other trees the larch is related to is the red pine, and the blue globe spruce.The larch is coniferous, and there are 10 or more needles in a bundle. Three distinguishing characteristics of the tree are that the bark is smooth at first and then becomes scaly, it produces a cone that is 3/4" long and egg-shaped, and it is coniferous but it looses tits needles in the fall. The wood is used for paper pulp, lumber, posts and railroad ties. http://en.wikipedia.org/wiki/Larix_laricina

=Biomolecules in Foods= The food I tested was lettuce. In the lettuce the simple sugars, starches, proteins, and the fats and oils were all absent. Another food that we tested was milk. We found that in milk there is proteins and fats and oils, but there was not any simple sugars or starches present.

I looked up potatoes, and it said that they had fat in them. In some tests potatoes tested negative for fats.

=DNA Extraction home work= 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, because different things could be different when they swished the Gatorade in their mouth. The amount of DNA extracted could be affected by if you bit your cheeks and what food you ate.

=DNA Replication Summary = There are many different steps in DNA replication. The first steps are for the leading strand of DNA. First, an enzyme called helicase breaks down the hydrogen bonds and unwinds the DNA strand. Then, small proteins attach to the single strands to keep the stands from coming together again. The next step is when an enzyme called primase attaches to the single strand that is leading the other. Where primase attaches is where DNA replication will start. The next step is an enzyme called polymerase binds to the leading strand where the primase made the starting point and replicates the DNA. The next steps are used to replicate the lagging strand of the DNA. First of all, just like in the leading strand primase makes a starting point for DNA replication. Then polymerase replicates the DNA but only makes small fragments called the okazoki fragments. Then between the fragments an enzyme called ligase fuses the fragments together. When all these steps are performed the original DNA is replicated.
