Genome - The genetic material of an organism or virus
Chromosomes - structures made of one DNA molecule and proteins
Somatic Cells - body cells
Gametes - reproductive cells
Chromatin - The complex of DNA and proteins that makes up eukaryotic chromosomes.
Centromere - Point on a chromosome by which it is attached to a spindle fiber during cell division.
Sister Chromatids - Identical copies of a chromosome; full sets of these are created during the S
subphase of interphase.
Mitosis - division of the nucleus into two identical daughter nuclei containing the same number of
chromosomes
Cytokinesis - division of the cytoplasm to form two separate daughter cells(immediately after mitosis,
meiosis I, or meiosis II.)
Meiosis - Cell division producing haploid gametes
Mitotic (M) Phase - mitosis and cytokinesis
Mitosis: Cell separates and divides chromosomes
Cytokines: Cell divides cytoplasm and organelles.
, Interphase - Cell grows, replicates chromosomes, produces new organelles and cyclins.
G1 phase - Cell grows, duplicates organelles, and gathers materials for DNA replication.
S phase - DNA replication occurs
G2 Phase - growth and final preparation for division, nucleus well defined.
Mitotic Spindle - a structure made of microtubules that controls chromosome movement during mitosis
Centrosome - A structure that functions as the microtubule organizing center and is important during
cell division, has two centrioles.
Kinetochore - A structure within the centromere containing the motor protein dynein. Moves the
chromosomes apart during anaphase.
Cell Cycle Control System - A cyclically operating set of molecules in the eukaryotic cell that both triggers
and coordinates key events in the cell cycle.
Cyclin - a protein that regulates the cell cycle
CDK - (Cyclin-dependent kinases) A protein kinase that is active only when attached to a particular
cyclin. Activity rises and falls depending on the concentration of the cyclin partner.
MPF - (Maturation-promoting factor) a protein complex required for a cell to progress from late
interphase to mitosis. The active form consists of cyclin and a protein kinase.
growth factors - Regulatory proteins, ensure that cell division occurs properly
Density Dependent Inhibition - crowded cells stop dividing
