Activities to Complete Draw a diagram of the cell cycle similar to the one in the primer and label the phases G1 S G2 and M Mark Note the phase in which chromosomes replicate Use Pop it beads to model the cell cycle including G1 S G2 and all the stages of Mitosis o Build a diploid set of homologous chromosomes where 2n 6 The two different colors yellow and red should represent maternal and paternal chromosomal contributions in each diploid cell i e in each homologous pair of chromosomes one chromosome will be yellow and one will be red The magnets will be used to represent centromeres After completing these activities you should be able to answer the following questions about Mitosis You can use chalk to draw circles on the lab tables to represent the cell membrane nuclear membrane and mitotic spindle as you model each stage in the cell cycle Note the circles might change as you walk through the different stages For each stage of the cell cycle including mitosis state how many chromosomes replicated chromosomes and chromatids are present Use the microscope and the slides of onion root tip sections to find and draw a plant cell in Interphase and each phase of Mitosis Prophase Metaphase Anaphase and Telophase label the nucleus if present and chromosomes if visible In hat stage does the nuclear envelope dissolve What are the chromatids called after going through anaphase in mitosis What are the resulting products of mitosis
