DNA extraction - science

 In science recently we have been focused on DNA and genes. One of our earlier activities around DNA was making the structure out of paper. If it was done right it would look like a spiral ladder if not done right it would look like a average ladder. Later on we extracted DNA from a kiwi fruit. you can extract DNA from a range of fruits with home appliances. Like salt, dish soap or instead of using dish soap it could be hand wash or shampoo all work well if done right.

To extract DNA form the kiwi fruit we separated the fruit form the skin and put the fruit in a zip lock bag. We fulled a about a half cup of water with salt and dish soap to create a solution the would be combined with the smashed kiwi fruit. Once the solution is added to the bag we made sure the bag we closed and carefully mixed it without making to many bubbles, that breaks up cells to extract the DNA. Then the mixture is put through a coffee filter about half a test tube if fulled with the mixture and rubbing alcohol is added enough to double the amount and a snot like substance is created which is the DNA from the kiwi fruit. We got a thin stick and picked some of it out.

    What a great blog post. Your explanation of the extraction process was great. This is extraordinarily topical right now.. why? How are we seeing the importance of this type of science right now?
