which of the following describes how RNA and DNA are used in mitosis? a. leads to the synthesis of proteins that assist in cell replication b. produce energy for cell division c. moves vesicles to the middle of the cell to form the cell plate d. forms spindle fibers that attach to chromosomes
Match the stage of mitosis with the correct description.   a.Microtubles that are attached to each chromosome shorten, pulling the sister chromatids apart. b.The chromosomes line up single file in the middle of the cell. Sister chromatids are clearly visible in this stage. c.The chromosomes that were pulled apart reach therir respective poles. The chromosomes decondense. The nuclear envelope re-forms. The cytoplasm with organelles divides. d.Chromosomes have replicated and appear as an "X". The nuclear envelope begins to break down. The chromosomes begin to condense into individual structures. e.Centrosomes move to the opposite ends of the cell and establish two spindle poles.The nuclear envelope is completely degraded by the end of this stage. The chromosomes are completely consensed by the end of this stage. f.Not actually part of mitosis; this stage is the part of the cell cycle that is not the mitotic phase. DNA is decondensed and appears diffuse throughout the…
Which of the following statements about mitosis is incorrect? a. Microtubules from the spindle poles attach to the kinetochores on the chromosomes. b. In anaphase, the spindle separates sister chromatids and pulls them apart. c. In metaphase, spindle microtubules align the chromosomes at the spindle midpoint. d. Cytokinesis describes the movement of chromosomes. e. Both the animal cell furrow and the plant cell plate form at their former spindle midpoint.
