Chapter 3 I. Inter phase Occupies 90% of the total cell cycle (majority of the cell cycle) 3 phases o G1 – growth o G2 o S – DNA replication Replication ensures that each new cell will receive identical genetic information to that present in the parent cell II. Mitosis Responsible for growth, replacement, development and maintence Mitosis divided into phases (continuous, takes about 1 hour) o 1. Prophase Divided into early, middle, and late prophase Centrosomes, centioles replicate (made up of microtubules that make up mitiotic spindle) anchor centrioles to plasma membrane by asthors. Nuclear membrane breaks up, genetic material is visible. o 2. Metaphase Chrosomes are lined up in the center of cell due to mitriodic spindles attatched o 3. Anaphase Centroimere splits results in 2 separate chromatids, then pulled by micro spindles on opposite sides of the cell o 4. Telophase Chrosomes on opposite side, nuclear membrane surrounds each group of chrosomes creating daughter cells (geneticall identical and identical to sell) Is typically followed by cytokinesis (division of the cytoplasm) o Exceptions: osteoclasts are multi nucleated cells
