The Flowering Dogwood is deciduous. It has smooth leaves. The leaves are 3-5 inches long, leaves are clustered towards tips of twigs, and the margins are smooth and wavy. Native Americans used the tree to create dyes and tinctures of scarlet. They used it to make tea also. They believed it would reduce fevers and ease colds. IT has been used to make forks. spoons, bowls, hay forks, hatchets, mallets, spindles, bobbins, other parts of spinning wheels, crochet hooks, knitting needles and a wide variety of small tools.

=Cedar Tree= The scientific name for the Cedar tree is //Cedrus.// The Cedar tree is related to different kinds of Pine trees. The Cedar tree is a coniferous tree. The needles are soft and fern like. They have cones on the tree, there are flowers on the ends of the needles and there are 15-45 clusters of needles on a branch.

That's why they make cedar chests out of cedar wood so that the moths can stay out of the chests.

=Biomolecules and Food= I tested egg whites. For the starches test I got negative. For the Benedict's test, egg whites doesn't have simple sugars. For the Biuret test came positive and it does have proteins. For the Sudan IV test it was negative for starches. One other person in my group did banana's. Starches and simple sugars are both present in the banana. Fats and oils and proteins were not present in the banana.



I was surprised the egg white was negative for starch because I thought there would be a lot of starch in it. I wasn't surprised it had no simple sugars because eggs do not have sugar in them. I expected it to have starches in it because I thought there would have been a lot of starch because eggs are healthy. For the banana I wasn't surprised there was sugar in it because it's a fruit and fruits have sugars in them. I was surprised there was no protein in the banana because some fruits have protein.

Nutrition Information: 0.23 grams of sugar; 3.6 grams of protein; 3% fats; .24 carbohydrates. None of them should have been positive instead of negative.

=Cheek Cell Homework Questions= Did everyone in your group have about the same extraction results? Yes. Why is this the case? We all used the same solutions and it turned out to be about the same. How is the amount of DNA that you extracted affected by your day to day activities? It affects your day-to-day activities because it tells our cheek what to do throughout the day.

=DNA Summary = This is how DNA replicates. Before it begins, the DNA is a double strand. Then, helicase comes in and breaks apart the hydrogen bonds. The single stranded binding comes next. It keeps the strands from going back together. Next comes the primase. That is the starting point for the replication of DNA. The polymerase then comes in. This binds and replicates the leading strand of DNA. There’s another step for the laggings strand. The primase breaks down the DNA. It is broken down into okazaki fragments. That is how the DNA is replicated.
