Proteins carry out the essential functions of life processes through systems of specialized cells. The structure of DNA serves as a code for the production of proteins through the process of protein synthesis. Protein synthesis is a biochemical process that uses information coded in DNA to construct proteins.  The central dogma illustrates the flow of genetic information in this process:  DNA-->RNA-->Proteins.  (Enduring Understandings of BIO.2d).This module was developed by Kris Scheible as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.
