1) Scientists isolate cells in various phases of the cell cycle. They isolate a group of cells that have 2 times more DNA than Gl phase cells. What is the most likely part of the cell cycle from which these cells were isolated? A) in the G2 phase of the cell cycle. B) between the G1 and S phases in the cell cycle C) in the late M phase of the cell cycle D) in the S phase of the cell cycle. 2) Which of the following statements is true regarding plant cell cytokinesis when compared to animal cell cytokinesis? A) The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins. B) Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase. C) The structural proteins of plant cells separate the two cells; in animal cells, a cell membrane separates the two daughter cells. D) Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow 3) Which statement describes correctly the difference between sexual and asexual reproduction? A) Asexual reproduction, but not sexual reproduction, is characteristic of only plants and fungi. B) In asexual reproduction, offspring are produced by fertilization without meiosis. C) In sexual reproduction, individuals transmit half of their nuclear genes to each of their offspring D) Asexual reproduction produces only haploid offspring. 1) Scientists isolate cells in various phases of the cell cycle.
