Cracking the Code of Life: Exploring DNA

Deoxyribonucleic Acid How does one long molecule control how our body works? DNA contains a code that tells our body how to make proteins. When you look at someone, you cannot see their DNA. However, you can see the proteins that their DNA helped make. How are these proteins made? What kinds of things do these proteins do in our bodies? Use the following links to explore DNA to find out. Explore a stretch of DNA Code and answer these questions: 1. What is the on/off switch? 2. What is a start codon? 3. What is a stop codon? 4. What is an intron? 5. What is an exon? Explore a Stretch of DNA Code DNA: The Stuff that Makes Chromosomes  How does DNA fit into chromosomes? And what do chromosomes mean for the human body? Explore this site to see how DNA fits into a chromosome. Answer these questions: 1. How long is the DNA molecule that fits in the nucleus of a human cell? 2. How does this much DNA fit into a tiny chromosome? <span style="background-color: #ffffff; color: #000000; font-family: 'Arial Black',Gadget,sans-serif;">Journey Into DNA <span style="background-color: #ffffff; color: #000000; font-family: 'Arial Black',Gadget,sans-serif;">How did researchers find out about the DNA code?

<span style="font-family: 'Arial Black',Gadget,sans-serif;">How does a cell know when it needs to make certain proteins? Are all genes constantly working--full time genes? Or can we call some genes part-time workers? Use this interactive to help you understand how RNAi works in an organism.
