BIOL 150 Chapter Notes - Chapter 12: Cleavage Furrow, Cancer, Protein Kinase
Document Summary
Cell division (new cells are formed by splitting of preexisting cells) Meiosis (leads to production of sperm and eggs) Mitosis (leads to production of all other cell types) Mitosis and meiosis are 2 fundamental different ways that nuclei divide before cell division. Cytokinesis (division of cytoplasm into 2 distinct cells) Dividing cytoplasm to create 2 complete cells. Chromosome (colored-body) (refer to these threadlike structures) Histones (chromosomes consists of single long dna double helix that is wrapped around proteins) Gene (region of dna in chromosome that codes for particular protein/rna) M phase (mitotic or meiotic) (cells are in process of separating their chromosomes) *cells actually spend most of their time in interphase* S (synthesis) phase (part of interphase) (process of copying the genetic material is separating, in time, from partitioning of replicated chromosomes during m phase) Cell cycle (describes orderly sequence of events that leads eukaryotic cell through duplication of its chromosomes to time it divides)
