Chapters 9 & 15 Lecture Guide The Cell Cycle Overview All cells posses a genome and a proteome The genome is the genetic information to make proteins with specific structures and functions The proteome is the collection of the proteins responsible for the structure and function of living cells Gene and protein regulation causes the proteome to be dynamic Proteins often undergo protein-protein interactions Cells must continually synthesize new molecules and break down unwanted components Multicellular Organization Tissue-group of cells having a similar structure or function Organ-collection of two or more tissues that perform a specific function or set of functions Basic Cell Processes 1. Cell division—eukaryotic cells progress through a cell cycle that leads to cell division 2. Cell growth—following cell division, cells take up nutrients and expand in volume 3. Differentiation—due to gene regulation, cells differentiate into different types of cells 4.
