Homework Help: Biology Lab Banana DNA

Posted by LC on Tuesday, April 1, 2008 at 7:53pm.

We did a DNA extraction lab of a banana. I was wondering, what exactly is the purpose of using mushed bananas, and how was water used as well (we used the water after using soap and salt, but I can't understand what the water did)? Thanks.

Mush the bananas to release DNA. Water dissolved the DNA (it is an acid).
