Finalized Notes Cells are small membrane bound units filled with concentrated aqueous solution of chemicals and given the ability of reproducing itself by dividing. Thus for this purpose the cells are the fundamental unit of life. If cells are modified to specific specialization they cause the cell to lose its ability to reproduce‚ as a result they end up depending on other cells for the basic needs. In all living things genes are stored in the DNA molecule‚ encoded in the same chemical code

Transcription The Central Dogma RNA Polymerase Ribosome DNA transcription replication RNA translation Protein One gene encodes one protein? (Beadle and Tatum‚ 1941) • • • Cellular machinery is largely made up of proteins. Proteins are made up of chains or sequences of amino acids. The sequence of these amino acids are "encoded" in the cell’s DNA. DNA is transcribed into RNA‚ which is then translated into protein. When one gene is mutated‚ one protein is affected (usually

Assumed Background: The course is designed for students with a basic understanding of the structures of the biologically relevant macromolecules and cell biology (as provided by the BIOL 130 prerequisite). This material will not be reviewed in class. Fundamental concepts of cell-cell communication and homeostasis from BIOL 273 will also be assumed‚ and will be reviewed only briefly
