This week for science, we learnt about DNA and DNA extraction. For this experiment, we had an option to use either strawberries or bananas since they are the fruits with the most cells. For the first step, we had to put the fruit of our choice in a zip-lock bag with a splash of water, a squirt of dish soap, and a teaspoon of salt, then smash till the fruit was a mushy liquid. Then we got a beaker with a straining cloth on top of it, and we slowly poured the mushy liquid into the beaker, as the chunks got strained onto the top of the cloth. After we had the liquid, no chunks, we poured it into the test tube and placed it in the test tube holder as we washed the beaker and the cloth we used. We were supposed to put a bit of warm water to activate it faster, but all the tapes in the science room were all not running hot water so we had to wait a bit. after maybe fifteen minutes, our teacher came with cold ethanol, dripping it down the side of the test tube at the dna cells slowly came to the top. Me and my friends expected there was going to be more dna cells or it was a differnt color but it was just a tiny ball when we mixed all the cells together.
