The DNA Game

Let me just start off by saying that I majored in chemistry in high school.  I know very little about biology and next to nothing about DNA, certainly not to the depth L is going.  Soooo I've had to do quite a bit of before hand research for some reference tools.

Of course the first thing L wanted to do is to build the famous double helix DNA model.  I'd found all sorts of different examples on Pintrest and we were all set to break out the pipe cleaners and beads when....

Side note here.  

Last October L got the Thames and Kosmos Genetics and DNA kit for her birthday in anticipation of our DNA studies.  I'd never really looked at it closely until we were about to do our model.  Well much to my delight they actually have a real plastic model you can make!  Yippee they also have a wonderful explanation of how DNA is built and how it goes together.  Using this and the BC Science 9 textbook L was able to create the DNA model.  It was a bit of a two person job to get it twisted correctly so all the bases fit together.

 After completing the model L had a good idea of the bases A and T and C and G joining together like rungs on the ladder and the sides being made up of phosphoric acid and sugar but all of those names are hard to remember.

I came up with this simple DNA game to remember the names of the bases and to really get a visual of how DNA is constructed.  L and I made up cards for the 4 bases and some sugar and phosphoric acid cards.  I also made up some question cards which contained questions like : What is the shape of DNA?  A: double helix.  I also had a lot of questions on the functions of the organelles of a cell.  

For the game play you work as a team to build a strand of DNA.  Each player takes 7 cards.  You take turns laying down a card to create the DNA structure.  If you don't have a card that works you have to answer a question.  If you answer correctly you pick up cards until you can go.  You basically continue on until neither player can go and you have your completed DNA strand.  This game worked wonderfully to help to remember all of the correct terminology as well as certain questions that needed review.  I keep changing the questions as we learn more information.

Stay tuned to see how we used the DNA game to learn about replication....
