SCIENTIFIC INQUIRY
Model building can be an important part of the scientific process. The illustration shown here is a computer-generated model of a DNA replication complex. The parental and newly synthesized DNA strands are color-coded differently, as are each of the following three proteins: DNA pol III, the sliding clamp, and single-strand binding protein. (a) Using what you've learned in this chapter to clarify this model, label each DNA strand and each protein. (b) Draw an arrow to indicate the overall direction of DNA replication.
