=Biomolecules in Food Lab= Spinach starch is present the color changed from green to golden brownish. Proteins is present, the color changed to blue. Fats and Oils were not present it wasn’t dark Simple sugars were not present, the color barely changed.


 * 1) I tested the Milk, in it Proteins and Fats were present but starch and simple sugars were absent. When I did the benedict test nothing happened that would show simple sugars were present, so simple sugar was absent. Than I did the Iodine Test, again nothing happened that would show starch was present, so it was absent. After, I did the Biuret Test the color changed to mauve which means Proteins were present in Milk. Finally, I did the Sudan IV Test there was a red circle around the top, which shows Fats and Oils are present. Ground Beef was another food tested in my group, it also had proteins and fats present and Starch and Simple sugars absent.

2. In testing these foods I found from other information vegetables were high in starches but mostly didn’t have sugars, proteins, and fats. Also that most meats had fats and proteins, but did not have sugars and starch. Most of the fruits had sugars in them, but had a low protein. A lot of the fruits also had fats and starches.

3.

4. What I found most surprising is milk doesn’t have simple sugars in it. I thought milk would because it kinda has a nice sweet taste to it. I also found the fact that most fruits didn’t have protein surprising. I thought fruit is what gave you protein.

5. I researched avocado and it doesn’t contain sugar or protein, it is also low in cholesterol and high in fat.

=DNA Cheek Cell 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? –

Everyone in my group had different results. Everyone has different DNA so no one would have the same extraction results. You get less DNA extracted if you scrape the side of your cheeks with your teeth or if you chew a lot of gum each day.

=DNA Replication Summary: =

** DNA Replication ** There are four steps to replication DNA. Step 1 is Breaking Hydrogen Bonds using Helicase, an enzyme. DNA kind of looks like a ladder, the parts on the outside are the backbones and the parts that hold them together are bonds. The Helicase breaks the bonds. The Second Step is Attach Single Stranded Binding Proteins to keep strands from going back together. The Third Step is the Primase attaches to the top Leading Strand, to give a starting point. The Primase is an enzyme that gives a starting point. Lastly, the Polymerase, enzyme that replicates DNA attaches to the bottom Lagging Strand, pieces of DNA called Okazaki fragments are than formed. Ligase connects the Okazaki fragments together. The DNA is than finished replicating.
