Models of Regulation
The functioning of living systems depends on proper regulation of the multiplicity of pathways in the cell and between cells. Whether it be determination of the right time for DNA replication and cell division, transcription of DNA into RNA to produce the proteins needed for various life-cycle stages and for reaction to environmental cues, response to external and internal signals, or development from unicellular to multicellular stages of an organism, proper regulation of a myriad of chemical reactions and noncovalent interactions is essential to life. Much of modern molecular and cellular biology has been devoted to understanding regulation.
