Embryonic cell cycles allow the rapid division of cells in the early embryo. These mitotic cell cycles are much shorter in length than the mitotic cell cycles of cells in a mature organism. In the embryonic cell cycles, mitosis takes approximately the same amount of time as it does in the cell cycles of mature cells. What do you think is a result of the embryonic cycle?
A. Resulting daughter cells do not contain the same genetic information as the mother cell in the embryonic cell cycles. B. Mother cells in the embryonic cell cycle spend the majority of their time in G0. C. Resulting daughter cells cannot form a mitotic spindle in the embryonic cell cycle. D. Resulting daughter cells are smaller than the mother cell in the embryonic cell cycles.
