Interphase (90% of a cells life preparing for division) * G1 cell growth, production of proteins and organelles * S DNA entailment (replication) * individual(a) chromosomes become multiply; made of 2 baby chromatids connect at centromere * G2 synthesis of proteins need for division * 2. Mitotic phase (where the cell splits) * Mitosis nuclear division * Cytokinesis cytoplasmic division * Stages of Mitosis * 1. Prophase * chromatin granule condenses into chromosomes * Sister chromatids joined at centromere * nuclear envelope and nucleolus disappear * Mitotic spindle forms (from pole to pole) (made of microtubules) * Centrioles (animal cells) carry to poles * mandrel microtubules attach to chromatids at kinetochore * 2. Metaphase *...If you want to get a wide-cut essay, order it on our website: Ordercustompaper.com
