The information molecules of cells, DNA and RNA, are introduced. The fundamental concept that genetic information codes for protein molecules is examined. DNA replication, transcription and translation into proteins are covered. The structure of proteins and their importance to biological function are introduced, with special attention to the proteins that act as biological catalysts. The central role of respiration to obtain chemical energy to maintain cells is examined with special reference to the oxidation of sugars and carbohydrates. BCHM 210A will cover material in greater depth than BCHM 210, with separate assignments being completed.
