DNA
DNA Notes:
DNA Alias:
Use the table at right to help you convert your name into its DNA Alias. Step 1: Write out your first name. Step 2: Find each letter of your name in the chart at right. Step 3: Look at the Simplified Codon column to find the DNA code for each letter. Step 4: Replace and write each letter of your name with its three-letter codon to create the gene for your name. Step 5: Now that you have the codons for the letters of your name, use the same table at right to find the amino acids each codon “codes” for. Write out the protein (the string of amino acids) your name spells out. Congratulations! You now have a DNA and protein alias for your name! |

DNA Games:
The pairing up of base pairs is crucial to the process of DNA copying itself (replication). Go to this “Build a DNA molecule” website. Follow the directions on the page to make your own DNA molecule.
Go to the following site to practice Replication. How fast can you go? How accurate can you be? Try all three organisms and see how well you do - which 3 organisms did you copy DNA for? How many genes and chromosomes did your three organisms have?

DNA Model:
Objective:
You will EACH create a paper DNA model that is 5 base pairs long.
Materials:
Scissors, tape, copies of puzzle pieces – A, C, G, and T, sugars, and phosphates
Directions:
Cut out 10 sugars, 10 phosphates, and 5 base pair sets of nucleotides. You may choose any five base pairs, but the pairs should match up the way they do in real DNA (look at the hints on the webpage above if you need it! Arrange your DNA model like a ladder - with sugar and phosphate sides that goi in opposite directions, and with the base pairs as “rungs” on the “ladder.” All the labeled sides of your pieces should be facing up. Using SMALL pieces of scotch tape, tape your models together, and put your name on the back of the model. If you are totally lost, look at the longer model displayed on the green wall in the classroom for tips.
