Core Competency Self-Assessment

My artifact that I chose for science 9 is my strawberry DNA lab. In this lab we extracted DNA from a strawberry cell. We did this by getting the DNA out of the nucleus in this lab from smashing the strawberries in a bag with dish soap, salt, and tap water. The smashing was to break up the plant cell walls in a bag. The dish soap was to break down the fats in the cell membranes and nuclear membranes so the contents of the cell and nucleus can be released. The salt breaks up proteins chains the bind around the DNA separated from the rest of the material. Since my teacher added more than the amount of strawberries everyone was supposed to have we had lots of strawberry DNA.  I think I demonstrated communication with my partner during this lab since we had to ask around for other partners opinions.
