Banana DNA Experiment

Variants of genes, called alleles, are responsible for differences in hair color, eye color, and earlobe shape. But this was a special step preparing for the addition of the dish soap. Its natural shape is called a double helix and when seen under extremely high-powered microscopes, it looks kind of like a ladder twisted into a spiral shape. You may see some bubbles and cloudy material moving around in the alcohol. I discarded the strawberry solids that remained in the cheesecloth. When you are done, take a closer look at the stuff on the stirrer.

Try to avoid making too much foam. The filtrate, or filtered solution from the bag, was then placed into a test tube. Do not mix the two layers together. Credits Banana and Strawberry image by Ralph Daily via Wikimedia Commons. Let's think of three of the main items we added to the bananas. The bag was then mashed again for one minute to mix in the buffer solution with the existing smashed fruit.

. There was really no source of error in this lab due to its simplicity. Think of fats and oils. Let the liquid from the mixture drain into the beaker then add the ethanol to the mixture. I added 10 ml of the extraction buffer solution to a plastic bag. Sorry, but copying text is forbidden on this website! All of these instructions fit within tiny packages within our tiny cells, so that is all way too tiny for anyone to ever really see or touch, right? You want the alcohol to form a layer on top of the banana mix, staying separated, so be careful not to pour it too fast.

Even though we might not look alike, all living things—bananas and people included—are made up of the same basic material. Strawberries have an octoploid genome, which means that the nucleus contains eight complete copies of each chromosome. The actual amount of water varied from group to group. Genetic Science Learning Center, University of Utah, accessed 12 Mar 2011. I crushed the bag against the table and formed a strawberry slurry.

It also controls many of the features that make an organism unique. Strawberries also contain pectinase and cellulase enzymes, which aid in the degradation of cell walls. I then broke down the strawberry cells into basic components: 1. I mixed 5 ml of detergent with. The kitchen scales which I used in my experiment were not precise as it the reading varied by one to two grams higher or lower from the actual reading of the weight. I removed the leaves and sepals from the strawberry and placed it inside the bag. These improvements to the food will make it disease resistant which will stop pests and other problems from destroying the food which will save farmers money as they would not lose any crops also scientist could genetically modify the fruit to be resilient to different weather climates so farmers could grow without worrying about their crops when droughts occur.

My averages of all three fruits range from a difference compared to the other fruit of 1. How about shampoo or body scrub? You do not want the mixture to become too foamy. Spin it in place so that cloudy layer spools around it. Enzymes may also be used to break up the proteins. The kiwi and the strawberry were the two that looked most a like and yet they were still different due to thickness and how well it stuck together. Spin the stirrer it in place to start gathering the cloudy stuff.

The strawberry produced enough juice and water based substance that no added water was needed, however the banana did not produce as much juice and a small amount of water was added. This added even more water based substance to the bag of mashed fruit. To have made the results more accurate, if I was to repeat the experiment I would have timed the amount I left it to drain so it would make my experiment consistent throughout the whole time. In SciActivitiesPage, accessed 5 Mar 2011. You can now throw out the coffee filter and its contents. Read on for observations, results and more resources. I filled a quarter of the test tube with strawberry liquid, and I added the same amount of ice cold ethanol.

Gently mix and slosh the saltwater and mashed banana together for 30 to 45 seconds. A detergent solution is then used to dissolve the cell membrane and nuclear membrane, which are composed of a phospholipid bilayer. Pour the banana liquid and alcohol down the drain and wash out the cup. This result could have been due to the amount of solution was present in the bag after the strawberry was mashed compared to the amount present in the banana bag. Better equipment such as a mortar and pestle could have been used to make it easier and get a better result.
