Melissa Wilson Sayres. 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. A water bath was prepared. 3) JFIF d d C Within every living organism, most cells contain a complete set of DNA instructions.
