Document Summary
Cell biology is an academic discipline that studies cells, the basic functional units of all known organisms. A cell is a unique complex structure a limited # of molecules are arranged together to perform life exercises. Cell biologists look at all aspects of the cell cell structure, cell organelles and membrane trafficking, cell cycle, division and death, cell signaling, and cell communications. Ultimate goal to understand how macromolecular systems and organelles work and cooperate to enable cells to function autonomously and in tissues. Nobel laureates of this millennium for discoveries related to cell biology: 2000 signal transduction in nervous system. 2001 key regulators of the cell cycle. 2002 genetic regulation or organ development and programmed cell death. 2003 channels in cell membranes and structural and mechanistic studies of ion channels. 2004 odorant receptors and the organization of the olfactory system. 2006 rna interference gene silencing by double-stranded rna. 2006 molecular basis of eukaryotic transcription.
