cycle of an average mammalian cell is illustrated below. How long did it take for the above-illustrated mammalian cell to complete one cell cycle? How long did the mitosis/cytokinesis phase (M phase) last? What % of the total cell-cycle time does that constitute to? What phase takes the longest time to complete during cell cycle and what % of the total cellcycle time does that constitute to? Explain why you think this might be the longest phase of the cell cycle. How long was the S phase? What is happening in the cell during the S

Choose all of the TRUE statements. Hint: 4 statements are true. Cytokinesis occurs the same way in both plant and animal cells. Sister chromatids are genetically identical. The term chromosome can be used to describe both chromosomes composed of one and two chromatids. Mitosis results in daughter cells that are genetically identical to the parent cell. All eukaryotic somatic cells are diploid. Cyclin dependent kinases are present but not active in cell cycle regulation without the presence of cyclin proteins. Chromosomes are always visible in the cell.
