PDF Experiment #6: DNA Extraction from Fruits - #hayalinikefet The ability to extract DNA is of primary importance to studying the genetic causes of disease and for the development of diagnostics and drugs. 20 milliliters (four teaspoons) of distilled water was then added to the mixture. 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. 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.

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. It is also essential for carrying out forensic science, sequencing genomes, detecting bacteria and viruses in the environment and for determining paternity.
