Extract DNA from fruit

This information can be used to improve crops so that they are more resistant to disease, insect invasion or changes in climate. Banana had a larger amount compared to the strawberry that was extracted. Two of the nitrogenous bases, adenine and guanine, belong to a group of compounds known as purines. They are there to protect the cell from invasion by viruses. Any cell consists of many parts but the parts that play the key roles are the nucleus, cell membrane, and cytoplasm.

Neither you, nor the coeditors you shared it with will be able to recover it again. Spin it in place so that cloudy layer spools around it. Draw and label the test tube and its contents, and work with your group to answer the questions on the Student Data Sheet. During cell division, this code is copied and passed to new cells. Banana is also used to depict Enset and Fe'i bananas, neither of which fit in to the abovementioned class.

Dna Extraction of Banana Essay

They are inhabitant to tropical South and Southeast Asia. The strained liquid will look nearly clear with a faint tan color. The alcohol was suspended above the cell solution and was clearer. Bananas are soft and dense, without a lot of stringy or gritty material which might be present in some fruits imagine a pear, for instance. The salt can dissolve in water, but not in alcohol. The cell membrane is like a wall that guards the cell. The tube was capped and inverted 5 times.

How to Extract DNA From a Banana

Nucleotides are composed of 5 carbon sugar attached to the phosphate group and a nitrogen containing base. This should produce approximately 10 to 15 ml of filtrate, which is sufficient for the 6 ml of ethanol in the last step. Pour the banana liquid and alcohol down the drain and wash out the cup. Blend for 15-20 seconds, until the solution is a mixture. In this experiment, a banana is treated with salt, water and soap.

If omitting the test tube, students can place their glass rod into the filtrate in a beaker and add the cold ethanol by allowing it to trickle down the rod. It is packaged into thread like structure known as chromosomes. Neither you, nor the coeditors you shared it with will be able to recover it again. Combine solutions from all student groups at this point. Each banana contains 10 to 14 hands, carrying 18 to 20 bananas each. Stir slowly to avoid foaming of the shampoo. The initial step to mash the banana in the solubilizing fluid requires only a few minutes.

This recipe makes enough for 10-5 oz cups. Chromosome cannot be visible even under the microscope if the cells are not dividing. Even though we might not look alike, all living things—bananas and people included—are made up of the same basic material. Both chains are held together by hydrogen bonding. Be sure to inform students of glass disposal procedures. Dependent Variable- We measure it by the way we put the materials in and how long we do. Next time I will use a better camera and science buffer instead of liquid soap.

The tube was placed upright at room temperature for five. During this time, what do you see happening between the alcohol and the banana liquid layer? Procedures Used in Experiment Once all materials were gathered by group members, each individual group began their experiment. The alcohol will trickle down on the side of the tube before the pooling strawberry extract. Each nucleotide has three parts: a deoxyribose molecule, a phosphate group, and a nitrogenous base. Name some parts from the banana cells that became trapped in the cheesecloth and discarded. I was wrong about my hypothesis, because I had said that the strawberry would have more. A long time ago bananas were imported in stems.

The purpose for adding the extraction buffer was to break the cell walls and disrupt the cells so that all the material inside the cell would be loosed and extracted from the cell. Cleanup You can wash the bag and reuse it. The remaining two bases, cytosine and thymine, are known as pyrimidines. 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. The salt shields the negative.

The banana does not contain fat, and can be eaten at every hour of the day. When you remove your finger it should form a well, where the juice can be poured. Two central biological questions arise from these requirements: how can the information for specifying an organism be carried in chemical form, and how is it accurately copied? Make sure everything has been crushed and there is no chunks left. Make a Smoothie After the students start their extraction activity, follow the recipe below to make a banana strawberry smoothie. Be sure to inform students of glass disposal procedures. Close bag and squeeze out air.
