Aim: To extract DNA from a banana using simple household items Hypothesis: DNA is found in the cells of every living organism. This lab was conducted in order to show and analyze the way DNA is extracted. The banana DNA was easy to see as it was a light pink/clear and it was chunky and had thick pieces when picked up with the skewer but it appeared shredded in the liquid. DNA is a component of living and once-living things. 8. Watch biologist Melissa Wilson Sayres as she shows you step-by-step how to extract DNA from a banana. cookie policy.

Because of their size, it is impossible to see a single DNA molecule with the naked eye. And how did we get inside the cells and get the DNA to stick together? 0000011509 00000 n Which is correct poinsettia or poinsettia? Even though the procedures vary considerably, they involve three main steps: lysis of cell wall, cell membrane and nuclear membrane, isolation of DNA from other cell inclusions, and purification of the extracted DNA. Genetic testing can best be defined as a process in which an individuals DNA is isolated and tested for the presence of specific genes or defects that could indicate the future onset of some disease. 4. 135 0 obj <> endobj A probable reason for this Each nucleotide has three parts: a deoxyribose molecule, a phosphate group, and a nitrogenous base. Strawberries are octoploid, which means they have eight copies of the DNA in their genome in every cell! w !1AQaq"2B #3Rbr For instance, the detergent or soap helps to break down the cells outer membrane, and the salt helps to separate the DNA from other materials in the cell. the so$ut#o" whe" the a$coho$, #s a%%e%.

For the genes DNA to subsequently influence an inherited trait, the stored genetic information in the DNA in most cases is first transferred to a closely related nuclei acid, RNA or ribonucleic acid. This could be a problem if two bacteria looked similar because they could easily. By continuing well assume youre on board with our The four nitrogenous are A(adenine), G(guanine), T(thymine) and C(cytosine). However, you may visit "Cookie Settings" to provide a controlled consent. and animals have DNA (deoxyribonucleic acid). 0000001162 00000 n Experiment to purify DNA from fruit Bananas, kiwis and strawberries all work well. My hypothesis was correct for strawberries producing the most DNA followed by kiwis and than bananas last. Retrieved from https://phdessay.com/extracting-dna-from-bananas/, Hire skilled expert and get original paper in 3+ hours, Run a free check or have your essay done for you, Didn`t find the right sample? Within every living organism, most cells contain a complete set of DNA instructions. You are looking at DNA! If the steps were altered then the yield or the amount of DNA per banana could have been very small because the DNA would get trapped inside the cells or bound to lipids. We are able to properly and successfully extract DNA from banana using cell disruption and separation techniques. However, it is nice because the students get to see and hold in their hand the substance they have been studying that seems so abstract and hard to believe it even exists. Place a very small sample of the extracted DNA on a microscope slide and place one drop of Aceto-orecin stain on the . 9>U0c4S7FK9>>Ns^|t_g7]}|qwwQvvpaZEU2pOUAK2wb)m-]v| DNA molecules are long, slender molecules that carry the heritable information of organisms on to future generations. >> << Possible Materials and Equipment Measuring cup . With 19 Apr 2016. The solution was stirred well and slowly. 6 (5 points) Which of the applications of genomics listed below can be used in agriculture? DNA extraction The concentrations of the extracted DNA was measured using the NanoPhotometer,UV/Vis spectrophotometer (Implen, munich, Germany) and the average concentration for 12 samples was 0.045g/l. Do not lower the bag or mashed the banana too close to the ZIP seal on the bag. The mixtures were filtered through cheesecloths. 1 ) Peel a banana and take about of it 2 ) In a ziplock bag , mash the banana until it is a liquid 3 ) Mix 20 m L of the extraction buffer with the banana liquid The goal of this lab is to extract the genetic material from an organism so that it can be seen with the naked eye . 10 minutes with: Explore how the human body functions as one unit in harmony in order to life //= $post_title /Filter /DCTDecode Body identification is a subfield of forensic science wherein investigators need to identify a body. Remove and discard the used coffee filter. 0000000016 00000 n * Elof Carlson (The Unfit), Mendels Legacy: The Origin of Classical Genetics, Cold Spring Harbour Laboratory Press, USA * Benjamin Cummings(2005), iGenetics: A Mendelian Approach, Pearson; University of Chicago, USA. Potential of independent assortment in meiosis I C. They reside on different chromosomes D. One gene often. What does soap do when you wash your hands. Three heaping teaspoons of the banana mixture that was made in the beginning of the experiment was then added to the shampoo, salt, and water solution and mixed with a spoon for five to ten minutes. The Essay on Human Genome Project Sequence Dna Information. These instructions are in segments of DNA called genes. 9 How does detergent help to break down DNA? Necessary cookies are absolutely essential for the website to function properly. When subjected to certain conditions, it is possible to collect large amounts of DNA to make it visible. Segments, or pieces, of DNA are called "genes." Hear Let this two-layer mixture sit for eight minutes. Updated on April 13, 2019 Extracting DNA from a banana may sound like a difficult task, but it is not very difficult at all. Some additional protocols for DNA extractions: Sex Influenced Female Dominant Inheritance, beakers 100ml and 2x250ml (or jars that same size), liquid dishwashing detergent (clear solution works better than cloudy), Make a 10% solution of dishwashing detergent in one of your 250ml beakers (make enough to fill the mortar half way), Add the 10% detergent solution to cover the fruit, Grind the banana in the soap solution until there are no lumps (this is the hardest part, have the students take turns), Fasten a coffee filter to the 250 ml beaker with a rubber band so there is room for the fruit to be poured into the filter, Pour the fruit and soap mixture into the filter and place in a cold place to filter, Clean up your lab area while you are waiting for the filtering to complete, Remove the filter and throw away the contents, Pour enough of the liquid into a test tube to fill it 2 cm high, Add twice the volume of 95% ethanol (try to layer the alcohol on top by gently pouring it down the side of the test tube), The DNA will precipitate in the boundary between the alcohol and the banana mixture as a cloudy mass. However, it is nice because the students get to see and hold in their hand the substance they have been studying that seems so abstract and hard to believe it even exists. Step 2: Put the banana into a bag. By clicking Accept All, you consent to the use of ALL the cookies. DNA extraction is a method to purify DNA by using physical and/or chemical methods from a sample separating DNA from cell membranes, proteins, and other cellular components. The total number of DNA for each fruit had a big variation between strawberries compared to kiwis and bananas with a difference of 5 and 6. How do I choose between my boyfriend and my best friend? %PDF-1.4 /SMask /None>> Motivation: Recent technological promotions in the field of genomics have resulted in Following Generation DNA Sequencing Technologies. And because the DNA doesnt dissolve in alcohol, this substance helps the DNA clump together in a separate layer. Bananas and strawberries are great choices. The DNA precipitates out of the solution when the alcohol is added. . The solution had to be blended for 15 to 20 seconds, until it became a dense mixture.
