DNA model

Had a very fun biology pratical today.We had to make a model of a DNA. I guess mine was the longest since ihad finished it very fast :P but it wasn't very good i thk. I have taken a picture of mine and a model of my teacher's DNA model.

A little bit of infomation on the DNA..You should be able to see "coloured" nitrogen bases
held together like rungs of a ladder by the sugar phosphate backbone. Red and Blue is Adenine(red) and Thiamine (Blue) while Yellow and Green is Cytosine (Yellow) and Guanine (Green). Of course, in actual life our DNA has no colour.
