DNA sequence of perticular gene

I have to build a DNA model, and need to base it off an actual DNA sequence, for an actual gene...I can't seem to be able to find anything I can model. Please help...

search for hemoglobin, click second link, view gene table, you will see a table that looks like the one here, click one of the numbers and you will have a portion of the dna that codes for hemoglobin

I have built many models of DNA. Get chicken wire, Styrofoam balls, and toothpicks. Cut two long pieces of chicken wire, stick the Styrofoam balls through the wire and move it down. Repeat process until you think there's enough (Let's say 12-20 on each side?). Take the toothpicks and color one half one color, the other a different color. This represents the nucleic acids (Thymine, Guanine, Cytosine, and adenine). Obviously you'll randomly color the other toothpicks, but be careful: only pair the correct bases together. A&T, G&C. Have only four different colors and use them for the same base every time. Then attach both sides using the toothpicks. Stick ball one with ball two of other strand, etc, until the end of all of them. Then GENTLY twist the entire helix to get the helical structure of DNA.

Hope this helps!
