- The following image shows the basic cross sectional structure of a 9 + 2 array in a microtubule. The two images below it show cross sections of the microtubule flagellum of sperms cells from a man affected by Kartagener syndrome and an unaffected man. Examine these images, then answer the questions that follow. What structure appears to be underdeveloped or missing in the microtubules of the sperm flagellum affected by Kartagener syndrome? A. Pairs of microtubules B. The dynein "arms" C. The plasma membranearrow_forwardWhich of the following options correctly describes the functions of both cilia and flagella? Excretion Protection Locomotion Body’s defense BENTEN: During meiosis I, pairs of homologous chromosomes align randomly along the metaphase plate before being separated. This process helps generate genetic variation in the offspring of sexual reproduction. Which of the following best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring? Random alignment increases the likelihood of crossing over between non-sister chromatids. Random alignment results in the formation of gametes that contain different numbers of chromosomes. Random alignment increases the number of possible chromosome combinations in the gametes. Random alignment results in the formation of some diploid and some haploid gametes.arrow_forwardWhich of the following statements regarding microtubules is FALSE? Microtubules are typically arranged in cells such that thoir plus (+) ends are directed towards the plasma membrane and their minus (-) ends are attached to the centrosomes. Microtubules are composed of 13 protofilaments that are arranged into a hollow cylinder. Microtubules are polar. Microtubule-binding proteins, such as Tau, bind to microtubules to destabilizo thom. Microtubules are inherently unstable and rapidly disassemble with low/ GTIP concentrations.arrow_forward
- Which of the following changes to the microtubule binding protein, Tau, commonly occurs in Alzheimerâ s and other neurodegenerative diseases? A Tau is hypo-phosphorylated and does not bind to microtubules to destabilize them. B Tau levels are so low in the cell that they only bind to some microtubules. C Tau is hyper-phosphorylated and does not bind to microtubules to stabilize them. D Microtubules are hyper-phosphorylated and do not bind to Tau.arrow_forwardThe drug taxol, extracted from the bark of yew trees, has an opposite effect to the drug colchicine, an alkaloid from autumn crocus. Taxol binds tightly to microtubules and stabilizes them; when added to cells, it causes much of the free tubulin to assemble into microtubules. In contrast, colchicine prevents microtubule formation. Taxol is just as pernicious to dividing cells as colchicine, and both are used as anticancer drugs. based on your knowledge of microtubule dynamics, suggest why both drugs are toxic to dividing cells despite their opposite actions.arrow_forwardA hand lens or magnifying glass is strong enough to view cell organelles try or falsearrow_forward

Kinesin 5 Kinesin 7 4 Kinesin 1 O Kinesin 13 O Kinesin 2 Previousarrow_forwardA classmate claims that there are the same number of cells first placed on a NA plate with their fingertip before and after incubation. They point out the number of colonies after incubation as evidence. Is this true or false, and why? Choose the best answer. True; the individual cells grow in size, but not in number, creating the colonies seen after incubation. False; there are more colonies after incubation than the number of cells first placed on the plate. False; the number of cells first placed on a dish with their fingertip is the same number of colonies seen after incubation, but the number of cells after incubation has increased. False; the number of colonies has no relationship with the number of cells first placed on the plate.arrow_forwardAll of the following pairs are well matched except one: Cilia and flagella : axoneomal microtubules Motor proteins: Dyneine and Kynesine Microtubule-organizing center : Mitotic and meiotic spindles Intermediate filaments : Locomotion, amoeboid movement,arrow_forward
- Which of the following statements about the function of the centrosome is FALSE? Microtubules emanating from the centrosome have alternating polarity such that some have their plus end attached to the centrosome while others have their minus end attached. Centrosomes contain y-tubulin ring complexes important for microtubule nucleation. Centrosomes typically contain a pair of centrioles made of short microtubules. Centrosomes are the major microtubule-organizing center in animal cells. Two centrosomes form the mitotic spindle during cell division.arrow_forwardThe drug taxol is extracted from the bark of yew trees. It binds tightly to microtubules and stabilizes them. When added to cells, it causes much of the free tubulin to assemble into microtubules. Taxol can be used as an anticancer drug. At the molecular level, what does the drug prevent? At the cellular level, what part of cell division does it prevent? Be specific.arrow_forwardExplain your answer for 1 to 2 paragraphs While many of us have an intuitive sense of the what is meant by “growth” in our everyday vocabulary, growth is an important concept in developmental biology as well. a) How does cell death fit into a discussion of growth? b) How is growth different from regeneration?arrow_forward
