Blueberry Hypothesis: A Scientific Experiment
Results During our experiment we were able to obtain data that showed that the raspberry had the highest DNA yield over all of the fruits at 1.93%. Our next highest DNA yield was at 1.11% and came from our blueberry sample. Although our blackberry had the third highest DNA yield there was a significant drop in our percentage to .921%. Based on our results the banana had the least amount of DNA yield with .138%.

Discussion The purpose of this experiment was to be able to better understand the properties associated with DNA in live organisms and to find out how to isolate and quantify DNA in plant materials using Dische diphenylamine. This particular experiment could be very useful to scientists as a similar procedure could help identify genetic diseases and could also aid in finding cures for those genetic diseases. Based on assumption our hypothesis was formed and it was believed that the banana would yield the most DNA after undergoing our test. We came to this assumption from the idea that the banana was denser than the other samples, and would …show more content…
In the very first steps of the procedure we were instructed to mash the sample into small pieces and there was a huge difference in the appearance of the banana and the other fruits. The banana was not only harder to mash but had a thicker consistency than the raspberry, blueberry and blackberry. After adding the Dische diphenylamine, the color could be recorded and we were also able to record the Abs600. From this point we were able to calculate the concentration, the total DNA yield and the percent DNA. From our DNA yield data our hypothesis could be proven incorrect based upon the fact that the banana actually had the smallest amount of DNA with .138% and the raspberry had the highest yield with 1.93%. Our graph clearly shows these yields and also helps prove our hypothesis to be

    Was Pete Anderson Guilty

    The botanist advised the state agent to use the size of the protein “compositase” to find the identity of the plant in the pot. This process uses electric currents to draw DNA out from the wells formed in the gel because the DNA is negatively charged and it would try to move through the gel to get away from the negative side of the electric current. This allows the scientists to see it’s behavior as it moves through the gel as the smaller proteins move more quickly than the larger ones. Since DNA is colorless the scientists stain the sample in order to visualize the protein and then they can compare the sizes and patterns of the three flowers to the sizes and patterns from the plant in the…

    Next, we completed tests 1 and 2 wich was basically to oibserve the structural characteristics of the plants and seeds through a microscope . Then we came up with an hypothesis for wich species would be most closely related to the botana curus. Thirdly, we looked at the slides and comapared the arrangements of the bundles. Next we completed test four wich had to do with the chromatography paper and sepperating the different colored pigmentsfor each plant. Then, we did test five wich tested the plants for a fizz to check if they have enzyme M. Test six was the simulated gel electrophoresis that would compare the DNA. Lastly, we changed the sequence of DNA code to make amino acid to understand our…

    BCH 369L: Biochemistry Lab Report

    This was done by melting a solution composed of 0.7% agarose in 1x TBE and 0.005% ethidium bromide, and pouring the resulting liquid into comb-containing gel tray until the thickness reached about 6 mm. Once the gel had been allowed to cool for about 20 minutes, it was removed from the tray, placed in a horizontal gel apparatus, and immersed in 1x TBE buffer. Next, three different solutions were prepared from an aliquot of HindII digested lambda DNA and 3 microliters of 6x loading dye, an aliquot of EcoRI digested lambda DNA and 3 microliters of 6x loading dye, and 1 kb DNA ladder and 3 microliters of 6x loading dye. The resulting solutions were then transferred into separate wells within the gel, and the apparatus was connected to a constant current source (45mA) for 60 minutes. After producing clearly visible bands, the gel was taken out of the apparatus and photographed with an ultraviolet light box (Displayed in Figure…

    Strawberry Extraction Lab

    DNA is the genetic information in organisms that codes for proteins, and controls the cells function. The DNA is a double helix molecule that is formed by various nucleotides which include Adenine, Thymine, Guanine, and Cytosine with sugar phosphate. Different organisms can have larger or smaller genes. DNA is also what makes up chromosomes during cell replication. Strawberries have a large amount of genes. The extraction solution which includes soap and salt is used to disrupt the cell’s plasma membrane and nuclear envelope, to make the DNA clump together. The salt breaks up the protein chains that bind the nucleic acids. DNA does not dissolve in ethanol, and the colder the ethanol is, the less DNA that will be broken down allowing us to view the DNA in the test tube.…

    Unknown DNA Restriction Enzymes

    These results were completed through the gel electrophoresis lab that was carried out. Gel electrophoresis is a lab technique used in biochemistry in order to separate out pieces of cut DNA. This process requires that you have an electrical field passing through the gel in a specific direction. To allow for charge to flow across, you must have something that will conduct electricity, a buffer that's usually composed of ions works as a conduit for the electrical charge. An agarose and TBE solution was prepared and used to completely cover the entire gel. The DNA has a negatively charged backbone because of all the phosphate groups so they moved towards the positive end of the gel…

    Mozart

    Wolfgang Amadeus Mozart was born on January 27th, 1756; in Salzburg Austria. Born with the full name Johannes Chrysostomus Wolfgangus Theophilus Mozart, he quickly shortened it to Wolfgang Mozart by his early teenage years. His father, Leopold Mozart, was the assistant concert master in the Salzburg royal court. While his mother, Anna Maria Pertl, was born into a family of wealthy community leaders. His sister Maria Anna, was given the knick-name of “Nannerl”. By mimicking her playing on the harpiscord, Mozart developed a strong concept of chords, until he was also playing alongside of her. Mozart started playing the violin when he was four years old, and was composing his own music by his fifth birthday. When Mozart became six, and when his sister was eleven, Mozart’s father started on their “tours” across Europe to showcase the duo’s young prodigal talents in 1762. They stopped in Paris, London, The Hague, as well as Zurich. When Nannerl became of age to marry, Mozart obtained the shot that kick-started his career.…

    Essay On Symbolism In Hills Like White Elephants

    Choosing which paths to take when confronted with a cross-road is a complicated but necessary process in life. This process becomes even more complicated when having to base decision-making with another person’s interest in mind. Often couples are faced with a forking path, sometimes putting their relationship on the line depending on which way to turn. In the short story “Hills like White Elephants,” Hemingway exemplifies this fact of life and relays this message to his readers by telling the vague yet compelling story about an American couple and the compromise that puts a strain on their relationship. Jig and the man stopped at a junction on their way to madrid, where they are forced to deal with the constant elephant in the room- Jig’s…

    Brecht Theories

    Bertolt Brecht, a German socialist, dramatist, stage director and poet believed that theatre should appeal to the spectators dialectics rather than there emotions. Brecht was heavily influenced by a wide variety of sources including Chinese, Japanese, and Indian theatre, the Elizabethans, Greek tragedy, fair-ground entertainments and much more. On the contrary, Brechts own theatrical theories and staging conventions were a direct revolt against the theatre practices of his day. With reference to his ‘epic' dramas; The Caucasian Chalk Circle and Mother Courage and her Children, along with comparison to Dramatic theatre, this response will debate the issues surrounding Brechts revolution of theatre.…
