Jerrell Taylor created a 3-D model of DNA replication using Block Art on his Ipod. He asked to use that instead of create a paper model and it turned out great. This assignment required the students to use base pair coding of guanine, adenine, thymine, and cytosine, and translate it into a DNA ladder. They then simulated the process of replication that occurs in the S phase of the cell cycle by splitting the helix and replicating the strands.(see the pictures below)
