flat =About me=

I like to draw, read, and write. One of my favorite things to do walk through woodland. I do my best and try to be nice to everyone. My favorite food is hamburger mac and cheese and my favorite drink is fruit punch. This is me.

=American Sycamore= My tree is the Sycamore. The scientific name for the Sycamore is //platanus occidentalis//. Some of the relatives of the sycamore are the Red Maple, Silver Maple, and the Yellow Poplar. The sycamore is a deciduous tree with 3-5 lobed, palmate leaves with an alternate pattern. Something that sticks out about the tree is the bark. The bark is whitish and peels off. The splotches wear the bark peeled off can be brown, green, or gray. Also interesting is are its leaves which are light green on top and a paler woolier green on the back and its twigs are at first green and hairy. A specific use for the tree is to stop erosion on river banks, wood for crates, and are used for landscaping in cities because they are resistant to pollution. http://en.wikipedia.org/wiki/Platanus_occidentalis =Shellbark Hickory= My next tree is the Shellbark Hickory. The scientific name for this tree is //Carya laciniosa//. This tree is related to the shagbark hickory, Pignut hicorky, and the mockernet hickory. It is a deciduous tree. The Shellbark Hickory's leaves are compound, pinnate with a toothed margin. Its leaves are a dark green on the top while on the bottom they are a paler yellow green and hairy. Another feature of the Shelbark is its twigs which are orange-brown, hairy, and often angled with many orange lenticels. Another Defining feature is that its fruit is the largest of the native hickories, 1 3/4" - 2 1/2". Some uses for the hickory are firewood, tools, and wind breaks for they have very strong roots that hold them in place. http://en.wikipedia.org/wiki/Hickory

=Biomolecules in Food Lab= - For my food I did banana. What I found out was bananas have fats and oils, starches, and simple sugars present in them but protein is absent in them. The first test for simple sugars took a little while but it did come out positive after I put the Benedict solution in, as for the starch it took less time than the simple sugars and in no time I could see the iodine turning black. I then put the biuret in the banana and let that sit before going to the teacher for the Sudan IV which also came out positive. I went back to the Benedict but could see no change. - Another test at my table was cannelini bean. The results came out that starch, proteins, and fat and oils were present in the cannelini beans but simple sugars were absent. - The meat such as liver and ground beef all seemed to be absent of simple sugars and starch but has fats and oils and protein. Fruit seemed to have simple sugars, but be absent of starch, fats and oils, and protein. Vegetables grown above ground seemed to have starch but was absent of simple sugars, fats and oils, and protein. Vegetables grown below the ground seemed to have starch and protein but was absent of simple sugars and fats and oils (in potatoes but there was some in cannelini beans). Dairy seemed to have fats and oils(absent in egg whites) and protein, but was absent of simple sugars and starch.

I always thought that since avocado was a fruit it did not have any starch but it did. What also surprised me was that there was starch in egg yolks. I thought that since the egg yolk was technically an embryo that it would not have any starch in it because I thought that starch was bad for you. - The thing that surprised me because they were not there was the simple sugars in milk. I thought they would be there because there is a sugar called fructose in milk but simple sugars did not show up in the tests. Another thing is that there was no starch in ground beef. I theought since it was in liver it would be in ground beef since they are both meats. - I did research on milk and I found out that it should have simple sugars in it so the test should have been positive and not negative. I did research on avocados and found out that they should have come up positive for protein.

=DNA Extraction Lab Homework= Not everyone in my group got the same extraction result. This may have been caused by how long the Gatorade was in our mouths or how much we chewed the sides of our cheeks. This is effected by our day to day activities because people who eat more might have more cheek cells and those who exercise might have less or more as they build muscle and loos fat in the face and body. It could also be effected if you are under a lot of stress and chew the inside of your cheeks when you are nervous or are really stressed out.

=Summary of Replication =

Hi, my name is DNA. That is short for Deoxyribonucleic acid. I am going to tell you how I am able to replicate myself or make a copy of myself that looks exactly like me! Scientist from all over the world have been looking to unravel my mysteries and finally found out how I make this twin. I use a process I call replication. I do replication because I hold all the blueprints for your body and I need to pass on these blueprints. During replication my friend helicase comes over and binds or attaches himself to me. Helicase is an enzyme. Enzymes are like the key that starts a reaction or something responding to something else. After he does this he begins to break apart my bonds, or the things that hold me together. This splits me in half so that I am t wo strips, the t wo halves of myself. One of my strips is called the leading strand because this one leads in replication or the making of a duplicate of me and the other strand is called the lagging strand because it is always a bit behind the leading strand. To prevent my two strips from coming back together, my buddies the single stranded binding proteins bind to me to keep me in those two strands. Next, another good friend who calls himself Primase who is also an enzyme attaches to me to give my awesome friend Polymerase III, another enzyme, a staring point to make a copy of my other half for both the leading and the lagging strand. The only problem is that my two stranded are something called “anti-parallel”. This means that they run in opposite or different directions. The only way that Polymerase III can replicate is in a 51 to 31 direction, which is the way that my leading strand runs. My lagging strand, however, runs 31 to 51 which means that it cannot get my leading half’s replication without help. But help it has in my four good friends, Okazaki fragments, RNA primase, DNA polymerase I, and Ligase. Okazaki fragments are pieces of DNA that are created when RNA primase creates RNA primer, which are starting points that allow Polymerase III to run 31 to 51 to create the Okazaki fragments which are fragments of DNA. Then Polymerase I turns the RNA primers into DNA fragments. These fragments are then fused, or bonded, by Ligase with a Phosphodiester bond which is just a fancy word for the type of bond that keeps my backbone together. Soon, I am complete again and have a new twin brother who goes off to spread our blueprints far and wide and make more brothers. The cycle never ends. Well I hope you enjoyed this story for I had fun telling it. Bye! THE END!
