Playing with DNA

Noah is learning about DNA in his biology class.  Last week we extracted DNA from split peas.

Yesterday we made models of DNA with pipe cleaners and beads.  Unfortunately, the cats were extremely interested in that process, so it took longer than it should have. 

 Shiloh carried off a chromosome in her mouth.

 I ended up making a separate chromatid with one gene on it to distract her from bothering Noah while he built his strand of DNA.

 Then I attached it to their toy, which kept them interested for a long time.
