Deoxyribonucleic acid – that’s what.  It is the magic code that describes all living organisms.  Did you know that bacteria, plants and animals all share the same genetic material?  The language of DNA has only 4 letters, and yet we still see millions of different species and variations within species.

To help you learn about the structure of DNA, you can read this and this.  We will also attempt to extract DNA from strawberries.  Here’s how.  And this is the rubric for writing out the method etc. Communication rubric for extracting DNA from strawberries lab

This is a big topic!  And an important one. 

We’ll start by looking at the structure of DNA, then studying two important processes – replication and protein synthesis.  I will give you some handouts in class, but here are other resources you might find helpful.  I will add to this post as we find more.

Watch this video on how to extract DNA from strawberries.  We’ll be doing it in class.

Next lesson we’ll be learning about the basic structure of DNA, and then we’ll extract some from strawberries.  This is a link to a video we’ll watch in class that describes how to perform this experiment.

Good news – there will be no full lab report to write up.  The only thing that you will need to submit is a detailed method written in step format.  You may use your camera to snap pictures of the different stages to help you remember the process if you like.
