cell cycle, Regulated sequence of events that occurs between one cell division and the next, cyclins, Chemical signals that trigger the movement from one phase to another, sister chromatids, Connected at the centromere until separated during cell division., cell growth, Occurs during G1 and G2 of interphase, cytokinesis, The whole cell divides and one nucleus moves into each cell to create two genetically identical daughter cells. In animal cells this involves constriction of the cytoplasm between the two nuclei and in plant cells a new cell wall is formed., chromosome condensation, The reorganisation of the long thin chromatin strands into compact short chromosomes during prophase., centromere, Where the cell’s spindle fibres attach., centrosome, This produces the spindle fibres (protein microtubules) in animal cells., centriole, A barrel-shaped organelle found in pairs in animal cells., kinetochore region, Part of the centromere which facilitates the attachment of spindle fibers during cell division that help in the proper segregation of chromatids., chromatin, DNA that has been wrapped up around proteins called histones. The result resembles beads strung together., chromosome, A highly condensed structure found in the nucleus of cells during Mitosis that carries genetic information in the form of genes.
