Biological Function: The relationship of structure to function is one of the major themes in biology. For each of the following pairs, describe the structure and then explain how the function is related to the structure: A. Enzyme structure/catalysis; B. mRNA structure/protein synthesis; C. cell membrane structure/active transport or facilitated diffusion. 


3/14/12: The debate articles can be found here. You may wish to look at this website as well, in addition to other sources for these ethical debates.
