DNA Workshop

Hair grows from your head, nonstop, day in and day out. The cells of your hair follicles somehow generate all of the protein that make up this hair. How is this protein created? The answers to these questions are DNA replication and protein synthesis. The activity in this section places you within the cell, involving you with the processes of DNA replication and protein synthesis.

Journey into DNA
This exploration allows you to travel to the tiny world of DNA. Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll also see the intricate bending and winding that takes place within a chromosome, which allows more than five feet of DNA to fit within the nucleus of a tiny cell.

Sequence for Yourself

At first glance, the method described below may seem a bit complex and even roundabout. Well, sequencing the human genome is not as easy as A-G-C. The concepts involved, however, are easy to grasp. "Sequence for Yourself" should give you a good idea of the general process.
