flat =About me:= Hi! My name is Hope. I am a Freshman in High School. My favorite subject is Math. My favorite color is purple. I like the Patriots, and Tom Brady! I play softball, and volleyball. Some people describe me as funny, and fun to be around. My bestfriends include Lexxi, Ashley, Darin, Daran, and Amber :)

=Choke Cherry:= Choke Cherry's scientific name is Prunus virginiana. It is related to the black cherry and pin cherry trees. The tree is deciduous. The type of margin is toothed, it is simple, and alternate. Three distinctive features are, it is round at the base, it has abruptly pointed tips and sharply serrate margins, and the leaves are bright green on the top and paler underneath. The use for it is, is that it produces cherries that farmers gather and eat. http://en.wikipedia.org/wiki/Prunus_virginiana

=American Chestnut:= American Chestnut's scientific name is Castanea dentata. It is related to the Alleghany Chinkapin and the Chinese Chestnut. The tree is deciduous. The type of margin is toothed, it is simple, and alternate. Three distinctive features are the branches are small, brown, with small, white, raised lenticles, the fruit is a prickly bur, and the nuts are flat one side. The tree is used for a variety of reasons. One reason is furniture, split-rail fences, shingles, home construction, flooring, piers, plywood, paper pulp, and telephone poles. http://en.wikipedia.org/wiki/American_Chestnut#Uses

=Food Lab Analysis:= I tested apple and egg yolk. In my tests for the apple, I found that it was positive for simple sugars and negative for proteins, starches, and fats and oils. In my tests for the egg yolk, I found that it was positive for simple sugars, proteins, starches, and fats and oils. Another food my group tested was the avocado. I found out that during the Benedict test, the avocado turned a darker green, and the benedict solution turn a darker blue. It is positive for fats and oils and starch. In the biuret test, the avocado stayed on top and the biuret solution went to the bottom. I was surprised when I saw that apples had sugar and egg yolks had fat. I thought there would be protein in a potato. In the apple and potato, the protein should have been positive instead of negative.

=Cheek DNA Lab Homework= 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, not every one had the same extraction results. This could possibly be the case because it depends on whether you eat or don't eat. Also, if you ate something cold or hot. Another reason could be if you have braces or not. The braces would keep the cheek cells in them, instead of them coming out of your mouth. The amount of DNA could be affected by your daily activities. It could be affected because, again by what you eat. Also, how much you drink. The DNA could be washed away if you drink right before you go to extract it.

=DNA Replication Summary = DNA, deoxyribonucleic acid, is a double - stranded molecule, which is the basis for heredity. The shape of it is like a twisted ladder. The 4 steps for replication are "break hydrogen bonds," "single stranded binding proteins attach," "attach primase," and "attach polymerase (begin replication)." The first step, "break hydrogen bonds", is when you take a strand of DNA and break it apart, creating a space for replication. The next step, "single stranded binding proteins attach", is when the helicase breaks apart the strand of DNA and single stranded binding proteins keep the strand from coming back together. The third step is "attach primase." A primase is an enzyme that gives a starting point for the replication, so it can occur which is attached to the leading strand. The fourth step is "attach polymerase." In this step, replication begins. The polymerase adds nucleotides to the 3' end of a chain. Replicated DNA can only attach to 3' (3 prime) ends. It can never attach to a 5' (5 prime) end, so DNA ligase has to come and attach the 3' and 5' ends together.
