- Biologists have long been interested in the effects of radiation on cells. In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro. Proceedings of the Royal Society of London, Series B, Containing Papers of a Biological Character 100:413419.Chemotherapy drugs such as vincristine (derived from Madagascar periwinkle plants) and colchicine (derived from autumn crocus plants) disrupt mitosis by binding to tubulin (the subunit of microtubules) and interfering with microtubule assembly and disassembly. Exactly what mitotic structure is targeted by these drugs and what effect would that have on cell division?D. centromere QUESTION 8 Match the stages of mitotic cell division to the descriptions of those stages. v chromosomes attach to spindle fibers across the middle of the cell chromosomes are not yet duplicated so chromosomes only look like a line, only one pair of centrioles in cell A. Telophase cell membrane is pinching in forming a peanut-shaped cell, daughter v chromosomes reach the poles and new nuclear membranes are forming around them B. Late Interphase C. Early Interphase the nuclear membrane is breaking down, chromosomes are |condensing, centrioles are building microtubule "highways" (spindle fibers) D. Metaphase E. Anaphase chromosomes are duplicated so chromosomes look like an "X", two pairs of centrioles and double the amount of organelles fill the cell F. Prophase v cell is dividing into two identical cells G. Cytokinesis daughter chromosomes are beginning their migration to the poles on spindle fibers QUESTION 9 How do the two cells formed by a mitotic cell division compare…

OeScience Labs, 20160200 7 The anticancer drug paclitaxel (Taxol), derived from the Pacific Yew, has many effects on mitosis. One of its most powerful effects is that it prevents disassembly of the mitotic spindle, which prevents spindle fibers from shortening. Which phase of mitosis would this directly affect?

- Question 3: A woman suffers from albinism and is also a carrier for haemophilia. Draw a well- labelled diagram of a cell in Metaphase depicting the relevant chromosomes associated with these conditions. Identify the specific chromosomes (consult previous lectures) associated with these conditions. Your diagrams should clearly indicate the chromatids, chromosomes, genotypes, alleles, and cell structure needed in Metaphase. Use A/a to indicate alleles associated with albinism and H/h for haemophilia.Number of Chromosomes in a Human Cell in Different Cell Cycle and Mitotic Phases For each stage of the cell cycle and mitosis, identify whether there are 46 or 92 chromosomes in a typical human somatic (body) cell.

Assume a single nondisjunction event involving the X chromosome occurs in a cell undergoing mitosis in a human female. First, consider the daughter cell with the smaller number of chromosomes: How many total chromosomes will this cell have? How many X chromosomes will this cell have? Next, consider the daughter cell with the larger number of chromosomes: How many total chromosomes will this cell have? How many X chromosomes will this cell have?

(a) Identify the point in mitosis at which separase cleaves the protein complex that holds sister chromatid pairs together. In normal cells, separase is kept in an inactive state until it is needed. Explain how the progression of cells past sequential cell cycle checkpoints and the activity of enzymes such as separase is controlled by interactions between two major groups of regulatory proteins.
