1 Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display The cell cycle is the series of events that transpire between one cell division and the next Slide number 1 G 1 : Cell grows in size, prepares for DNA replication S: DNA replication G 2 : Cell prepares for division M: Mitosis 1. Breakdown of nuclear membrane 2. Condensation of chromosomes 3. Attachment of chromosomes to mitotic spindles Daughter cells Centrosome Cell membrane DNA Nuclear membrane Mitotic spindle Condensed chromosome Spindle pole
