This week, we discussed the structure and history of DNA. We learned how DNA replicates and how DNA nucleotide bases pair up (like puzzle pieces). On Wednesday, we built an edible model of DNA based on our knowledge of its structure. On Thursday, we discovered how the DNA code actually works. We discussed how 3 DNA bases code for an amino acid and that a group of amino acids make up a protein (the chemical messenger that tells the cell what to do). We even had the chance to "view" the DNA of a pea when we did our DNA extraction lab on Friday. When you get those labs back next week, just remember that you can take the "recipe" home and try to extract DNA from other sources!
Next week we will talk about genetic engineering and watch a great video on cloning, DNA forensics, and more! We will also begin picking out topics for genetic disorder projects.
