What You Need Banana Salt Warm water Liquid soap Blender Toothpicks Strainer Glass jar Rubbing alcohol Knife Here's How Write reflection paper about this question. %%EOF When we added. The DNA kiwi extraction shows how simple it may be to extract DNA from a living organism which is very essential because DNA gives important information DNA. In 1944, a group of scientists led by Canadian biologist Oswald Avery performed an experiment that would determine which molecule in a heat-killed bacterium was most important for transformation to occur. 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 lab was conducted in order to show and analyze the way DNA is extracted. 1 1 . cite it. PDF Banana DNA Extraction - Fleet Science Center The liquid soap is added to help break down cell membranes to release the DNA. 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. /Filter /DCTDecode The solution had to be blended for 15 to 20 seconds, until it became a dense mixture. 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.

Cells reproduce in part by passing deoxyribonucleic acid (DNA) from parent cells to offspring cells. Each living organism has its own unique DNA sequence. 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.
