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.arrow_forward

DNA replication occurs between metaphase and anaphase, doubling the number of chromosomes.

When done, there should be at least 50 marks on the table (one mark for each cell). You may need to count more than 50 to find at least one of every phase. Calculate the proportions, and estimate the amount of time spent in each phase and subphase. The table will lead you through how this works. Take the number of cells in a particular phase, divided by the total number of cells examined (i.e., 50—or more), then multiply by 24 (the number of hours an average onion root tip cell takes to complete the entire cycle. This should give the hours a cell spends in each phase. Again, this assumes, that the entire cell cycle for onion root cells is 24 hours. This time can vary in different organisms.
