The filtration step (pouring the mixture through the strainer) allows for the collection of the DNA and other cellular substances. 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. Do this for 30 to 45 seconds. Well, not entirely. And because the DNA doesnt dissolve in alcohol, this substance helps the DNA clump together in a separate layer. Then the bananas were mushed more. The enzymes in softens the phospholipids in the cell membrane and denatures the DNAse Test 2 Amount of DNA extracted Figure 1.

What You Need Banana Salt Warm water Liquid soap Blender Toothpicks Strainer Glass jar Rubbing alcohol Knife Here's How Gene: a region of DNA that instructs the cell on how to build protein(s). DNA is a component of living and once-living things. Cells reproduce in part by passing deoxyribonucleic acid (DNA) from parent cells to offspring cells. /4 When looking at DNA extraction,the key steps for isolating DNA from a plant cell or animal cell is to the solution is minimal remove the banana residue and transfer 5mL of the filtrate into a separate dry gas tube. Experiment to purify DNA from fruit Bananas, kiwis and strawberries all work well. The test tube solution. We even have genes in common with the banana plant! The mixtures were filtered through cheesecloths. If you took all of the DNA out of some middle-sized organism (or part of an organism, like a piece of fruit),you could see and even touch DNA. The bananas were mushed carefully to avoid the bag from breaking. $4%&'()*56789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz ? The salt will help the DNA stick together once it is out of the cells. We manage to learn basic DNA extraction processes. * To observe the extraction of genomic DNA from plant cells. 0000006862 00000 n Each living organism has its own unique DNA sequence. The test tubes were carefully handled to avoid shaking. 0000002685 00000 n During the procedure of the lab, a ratio of one banana per one cup (250 milliliters) of distilled water had to be mixed together in a blender.
