Science 9 – My science 9 classes built a paper model of DNA, with the phosphate, sugar and base pairs coloured in holiday colours. One of the parts of reproduction I’ve emphasized so far is the idea that DNA makes up chromosomes, sections of chromosomes make up genes, and genes code for proteins. As part of this process, RNA are small pieces of code that exit the nucleus. I jokingly turned our cutting of the DNA model (which has a copper wire structure) into an analogy of making RNA, where the RNA exits the nucleur pore (the classroom door). Each student had to cut a piece of DNA and carry it out to the garbage bin outside the classroom. Happy Holidays Everyone!
