Chromatid - Study guides, Class notes & Summaries

Interphase - cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases G1 phase - the cell grows in size and organelles double in size S phase - DNA replication ("S"= synthesize) G2 phase - cell growth, production of enzymes and other proteins two categories of mitosis - 1. karyokinesis (division of cell nucleus) 2. cytokinesis (division of cytoplasm) prophase - 1. chromatin condenses to form chromosomes; nuclear membrane and nucleoli disapp...
