Prelab assignment for Mitosis and Meiosis lab 1. Differentiate… Prelab assignment for Mitosis and Meiosis lab 1. Differentiate between the terms “mitosis” and “cytokinesis” by defining both terms. 2. Multiple choice – At the end of which phase(s) of the mitotic cell cycle does each chromosome consist of two sister chromatids? Indicate all correct answers – more than one answer is correct.a) G1 of interphase                   b) G2 of interphasec) anaphase                              d) metaphasee) prophase                             f) telophase  3. Which stage of mitosis/meiosis is most often associated with cytokinesis? Please explain.  4. Explain what is meant by a “First polar body” which is a product of meiosis in humans during egg cell production. How many mature egg cells (ova) are produced for every Oogonium undergoing meiosis? 5. List some information about sperm cell production by healthy human males as indicated in the lab manual. How many mature sperm cells are produced for every Spermatogonium that Does that undergo meiosis?       Mitosis and Meiosis post-lab  (2 points) Write a description of the chromosomes within the cells of a diploid plant with 8 chromosomes per diploid cell at the end of each phase of meiosis by filling out the table below. Recognize that cytokinesis is completed by the end of telophase and that two cells will be present for every cell that enters telophase.number of chromosomes in one cell      number of chromatids per chromosomeProphase IMetaphase IAnaphase ITelophase IProphase IIMetaphase IIAnaphase IITelophase II  3. A. Some specialized cells such as neurons and red blood cells lose their ability to replicate when they mature. Which phase of the cell cycle do you suspect is terminal for these cells? Why?B. What special event does interkinesis (interphase between meiosis I and meiosis II) lack compared to premeiotic interphase?    Science Biology BIOL 1615 Share (0)
