Kara+S

flat = = = About Me = Hello, my name is Kara! I am a freshman at Punxsutawney Area High School. I'm a pitcher for softball and I play first base. I enjoy hanging out with friends, listening to music, running, playing sports, and sleeping. My favorite school subject is probably Biology, although I don't mind any of the subject unless I don't understand them. I am a very social person and I love to talk. My favorite season is Summer because it's warm and we don't have school. Although winter is really pretty because of the snow on the trees, I dislike it because of it being so cold! That's a little about me, thanks for checking out my page!

= Eastern White Pine = Eastern White Pine, also known as //Pinus strobus,// is a coniferous tree, which means that the leaves stay on all year long. This is the only pine tree that has 5 needs in it's bundle. Occasionally, it has 3 or 4, but that is rare. The needles are flexible, bluish-green, finely serrated, and 2" - 5" long. The tree trunk is a darker color and it's grooved and scaled. The cones are 5" - 8" long, they have no pricks on them, and they are slightly curved. White pines are related to the Pines, Firs, Larches, Spruces, and Hemlocks. White Pines can be used for Christmas trees. The pine resin has been used to waterproof baskets, pails, and boats.

= Willow tree = A Willow Tree, also known scientifically as //Salix alba//, is a deciduous tree. The leaves on the Willow tree have serrated margins, and the leaves are simple and alternate, but they also have two small opposite leaves. The leaf petioles are short, and the leaves are feather-veined. The roots of the tree are remarkable for their toughness, and the tree bark is watery. Willow is grown for biomass bio fuel in some nuclear businesses. The leaves and bark of the willow tree have been used as aspirin, for aches and fevers. They are also used in the manufacture of boxes, brooms, chairs and other furniture, dolls, flutes, poles, wands, and whistles.

= Cheek Cell DNA Homework = Everyone in my group did not have the same extraction results because nobody’s DNA is the same and everyone’s is different. Also, the amount of cheek DNA could vary depending on how much your scraped your cheek and how much DNA you got from it. The amount of DNA could be affected for many reasons. If you ate before taking that test, you could have gotten more DNA from your saliva. If you wear braces, then more DNA would get into your mouth from your braces rubbing against the side of your cheek. If you chew gum, then you could get more DNA out of your mouth because you could rub your tongue and gum against your cheek.

= DNA Replication Summary = In DNA, there are four base pairs called Guanine, Adenine, Cytosine, and Thymine. Adenine and Guanine always pair together and they are called purines. Cytosine and Thymine always pair together and they are called pyrimidines. DNA has two strands called the leading strand and the lagging strand. For DNA replication to happen, the first step is the enzyme, helicase, breaks the hydrogen bonds that hold the base pairs together. In order for the two strands to stay apart from each other, single stranded binding proteins get attached to both the leading strand and the lagging strand. The third step in DNA replication is that the enzyme called Primase attaches to the leading strand and binds and forms a starting point for replication. The last step is for the enzyme called polymerase to bind and replicate the DNA. The leading strand is the main strand of the DNA double helix. The leading strand is the strand that replicates continuously. The leading strand and the lagging strand replicates in the opposite directions from each other. The lagging strand has fragments of DNA called Okazaki fragments, and lastly the enzyme “ligase” joins and binds the Okazaki fragments together.
