The BLANK is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division
  • cytokinesis
  • centrosome(s)
  • sister chromatid(s)
  • mitotic spindle(s)
In eukaryotic cells, chromosomes are composed of _____.
  • DNA and proteins*
  • kinetochore(s)
  • sister chromatid(s)
  • interphase
DNA replication produces two identical DNA molecules, called BLANK, which separate during mitosis
  • sister chromatid(s)
  • centrosome(s)
  • kinetochore(s)
  • chromatin
The beginning of anaphase is indicated by which of the following?
  • interphase
  • mitotic spindle(s)
  • Cohesin is cleaved enzymatically.
  • Duplicated chromosomes attach to the plasma membrane.
A cleavage furrow is _____.
  • a groove in the plasma membrane between daughter nuclei
  • Duplicated chromosomes attach to the plasma membrane.
  • interphase*These are the events of interphase.
  • the mitotic phase*The mitotic phase encompasses both mitosis and cytokinesis
Which of the following correctly matches a phase of the cell cycle with its description?A- G2: cell division B-M: duplication of DNA C-G1: follows cell division D-S: immediately precedes cell division E-All of the above are correctly matched.
  • Plant cells deposit vesicles containing cell-wall building blocks on the metaphase plate; animal cells form a cleavage furrow.
  • G1: follows cell division*After mitosis and cytokinesis, the newly formed daughter cells enter the G1 phase.
  • the mitotic phase*The mitotic phase encompasses both mitosis and cytokinesis
  • Duplicated chromosomes attach to the plasma membrane.
During mitosis, microtubules attach to chromosomes at the BLANK
  • interphase
  • kinetochore(s)
  • centromere(s)
  • centrosome(s)
Which of these phases encompasses all of the stages of mitosis but no other events?
  • This is mitosis
  • cytokinesis
  • Duplicated chromosomes attach to the plasma membrane.
  • centrosome(s)
Cells will usually divide if they receive the proper signal at a checkpoint in which phase of the cell cycle?
  • Duplicated chromosomes attach to the plasma membrane.
  • the mitotic phase*The mitotic phase encompasses both mitosis and cytokinesis
  • G1*In mammalian cells, this checkpoint is termed the restriction point.
  • mitotic spindle(s)
Phases of the cell cycle
  • a groove in the plasma membrane between daughter nuclei
  • Many organisms contain cells that do not normally divide. These cells exit the cell cycle before the G1 checkpoint.Once a cell passes the G1 checkpoint, it usually completes the cell cycle--that is, it divides.The first step in preparing for division is to replicate the cell's DNA in the S phase.In the G2 phase, the centrosome replicates.In early M phase, the centrosomes move away from each other toward the poles of the cell, in the process organizing the formation of the mitotic spindle.At the end of the M phase when mitosis is complete, the cell divides (cytokinesis), forming two genetically identical daughter cells.
  • They need both if they are producing animal gametes.*The form of cell division that produces animal gametes is meiosis, not mitosis. The production of gametes in plants is a function of both mitosis and meiosis.
  • This is mitosis
How is plant cell cytokinesis different from animal cell cytokinesis?
  • the mitotic phase*The mitotic phase encompasses both mitosis and cytokinesis
  • Plant cells deposit vesicles containing cell-wall building blocks on the metaphase plate; animal cells form a cleavage furrow.
  • interphase
  • G1: follows cell division*After mitosis and cytokinesis, the newly formed daughter cells enter the G1 phase.
Which of the following is found in binary fission but not in mitosis?
  • the mitotic phase*The mitotic phase encompasses both mitosis and cytokinesis
  • This is mitosis
  • Duplicated chromosomes attach to the plasma membrane.
  • G1: follows cell division*After mitosis and cytokinesis, the newly formed daughter cells enter the G1 phase.
