Chapter 9 Flashcards
chromatin
the complex of DNA that makes up a eukaryotic choromosome
division of the cytoplasm
cytokinesis
during which phase is DNA replicated
during the S phase of interphase
during interphase, the genetic material of a typical eukaryotic cell is
dispersed in the nucleus as long strands of chromatin.
the chromosomes cannot be distinguised individually because they are still in the form of loosely packed chromatin fibers.
if a normal human somatic cell is just about to divide, it has how many chromatids?
92
mitotic spindle breaks down and the chromatin uncoils
telophase
formation of the spindle fibers, the condensation of chromatin and the disappearance of the nucleolus
prophase
chromatin cannot be seen, spindle not yet begun to form.
interphase
what happens during prometaphase (mitosis plant cell)
nuclear envelope fragments and the kinetochores attach microtubules
fragments of the nuclear envelope begin to reassemble along with portions of the endomembrane system
telophase
in a human skin cell that is going through the cell cycle, when do the centrosomes separate?
prophase
in animal cell mitosis, the cleavage furrow forms during which stage of the cell cycle
cytokineses of telophase
mitosis
division of the nucleus
cytokinesis
division of the cytoplasm
meiosis
variation of cell division that creates gametes
