- Which statements are true? Explain why or why not.1 Since there are about 1013 cells in an adult human,and about 1010 cells die and are replaced each day, webecome new people every three years.2 In order for proliferating cells to maintain a rela-tively constant size, the length of the cell cycle must matchthe time it takes for the cell to double in size.3 While other proteins come and go during thecell cycle, the proteins of the origin recognition complexremain bound to the DNA throughout.4 Chromosomes are positioned on the metaphaseplate by equal and opposite forces that pull them towardthe two poles of the spindle.5 Meiosis segregates the paternal homologs intosperm and the maternal homologs into eggs.6 If we could turn on telomerase activity in all ourcells, we could prevent aging.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.in term of signal transduction how cell cycle/division is controlled?? ((while you are answerig plz write the refrence.))
- Choose all of the TRUE statements. Hint: 4 statements are true. Cytokinesis occurs the same way in both plant and animal cells. Sister chromatids are genetically identical. The term chromosome can be used to describe both chromosomes composed of one and two chromatids. Mitosis results in daughter cells that are genetically identical to the parent cell. All eukaryotic somatic cells are diploid. Cyclin dependent kinases are present but not active in cell cycle regulation without the presence of cyclin proteins. Chromosomes are always visible in the cell.Kinetochores control the transition from metaphase to anaphase. Why is this statement true? Question 7 options: a) Anaphase will only begin after the M checkpoint where all the kinetochores and mitotic spindle have correctly attached. b) Anaphase will only begin after the M checkpoint where all the mitotic spindle have correctly formed. c) Kinetochores bind to microtubules in monotelic attachment to the sister chromatids. d) Kinetochores bind to microtubules in syntelic attachment to the sister chromatids. e) Kinetochores will halt at the M checkpoint to weaken the mitotic spindle formation, which is the event that initiates anaphase.Which of these are cellular activities that sustain a single-celled organism through its lifetime? Select all that apply. A. Increases in cell size and volumeB. Processes by which individuals produce offspringC. The transmission of DNA to offspringD. Development into a multi-celled adult
- Passage of cells from G1 through R to S depends on the interaction of various signal molecules, proteins and enzymes which regulate the cell cycle.

Which of the following events do you predict will happen? circle all that apply Select one or more: a. Uncontrolled cell replication may result b. Retinoblastoma protein will be continuously active c. The cells will be stuck in G1 phase d. The cells will begin to replicate their DNA e. Cyclin dependent kinase (Cdk) will be continuously active6. Which best-described checkpoint? A. A site in the cytoplasm where proteins are inspected for mutationsB. Either G1, S phase, G2, prophase, metaphase, anaphase, or telophase.C. Specific stages where further progress of the cell cycle can be haltedD. Any step where the cell cycle is blocked by a mutated proteinThe cell cycle of an average mammalian cell is illustrated below. How long did it take for the above-illustrated mammalian cell to complete one cell cycle?How long did the mitosis/cytokinesis phase (M phase) last? What % of the total cell-cycle timedoes that constitute to? What phase takes the longest time to complete during cell cycle and what % of the total cellcycle time does that constitute to? Explain why you think this might be the longest phase of thecell cycle.How long was the S phase? What is happening in the cell during the S phase?
- Biopsies from aggressive cancers often have cells that contain several nuclei per cell when viewed through a microscope. Which scenario could explain how such a multinucleated cell might have come to be? (a) The cell underwent repeated mitosis with simultaneous cytokinesis. (b) The cell had multiple S phases before it entered mitosis. (c) The cell underwent repeated mitosis, but cytokinesis did not occur. (d) The cell underwent repeated cytokinesis but no mitosis. (e) The cell actually went through meiosis and not mitosis.What finalizes cell fission and must be coordinated with the site of nuclear division. This coordination is espe-cially important in cells undergoing an asymmetric division.3. G1, S and G2 constitute the largest part of the cell cycle. Which does NOT happen during this phase? A.
