In this lab, you will determine the amount of time a cell spends in each phase of mitosis and interphase by counting the number of cells in prophase, metaphase , anaphase and telophase. Let’s review the Cell Cycle: Interphase and M phase….. Cells from Whitefish blastula undergoing mitosis. Can you identify interphase, prophase, metaphase, anaphase and telophase? Mitosis and Cytokinesis As you watch the animation, look for when chromatin, chromosomes and sister chromatids are present. As you watch the animation, note what happens to the cell in each phase. As you watch the animation, can you describe what is happening to the amount of genetic material. If you were absent or want to review the “Determining the Time for Mitosis” lab, you can use the links below to perform the lab again. Time for Mitosis Lab Be sure that all data is recorded on the data table. Complete any calculations on the data table. Answer all lab questions on the lab. Do the following: If the total time for onion root tip cell cycle is 1,440 minutes, determine the amount of time each cell spends in prophase, metaphase, anaphase and telophase using the data from the data table. How much time is spent in M phase and Interphase?
