Basic genetic concepts and topics. Structure, function, and interaction of DNA and RNA. Replication and mutation of DNA. Regulation of gene expression. Structure and function of eukaryotic cells, chromosomes, and their mutation. Transmission and inheritance of simple traits, molecular traits, and the calculation of molecule size through electrophoresis. Labs use breeding experiments and molecular biology. Current application of molecular genetics to mutations, populations, evolution, or disease and development may be discussed. Prerequisites: BIO 125/125L and CHE 103/103L with a grade of `C' or higher.
