1) What phase of mitosis is this? Answer: 2) What is the indicated structure 1? select one. a. chromosome b. chromosome with two sister chromatids c. centrioles/centrosome d. spindle fibres e. metaphase plate 3)If the diploid (2n) number of this cell is 8 how many chromosomes are present? 4) If the diploid (2n) number of this cell is 8 how many sister chromatids are present? 5) If the diploid (2n) number of this cell is 8 how many homologous pairs are present?
Looking at the the time intervals in the figure given, compare the time spent in mitosis with the time spent in gap1 in human liver cells. A. less time is spent in G1 than in M B. a little more time is spent in G1 than in M C. The cell spends 10 hours less in G1 than it does in M D. The cell spends 10 hours more in G1 than it does in M
With regard to the process of mitosis, which of the following pairs is NOT matched correctly? a. Interphase - the cell grows, chromosomes replicate, and proteins are produced to prepare the cell to divide Ob. Prophase - chromosomes condense, and the nuclear membrane dissociates/breaks down c. Metaphase - chromosomes move toward opposite poles (or sides) of the cell d. Anaphase - sister chromatids separate e. Telophase - two distinct nuclei are formed; this is the stage immediately before cytokinesis O O O
The diagram below shows a model for the normal regulation of the transition to anaphase during mitosis. 1. Signals are released by unattached kinetochores that cause MAD to bind CDC20. MAD CDC20 6. Chromatids separate as mitosis procoeds to anaphase. COHESIN 3. The APCCDC20 CDC20 complex ubiquinates Securin. APC 2. When all kinetochores are attached, MAD releases CDC20 which then combines with APC UBIQUITIN SEPARASE . Separase destroys Cohesin APC SEPARASE SECURIN 4. Securin is destroyed, releasing Separase Your analyses of cancer cells that do not regulate this transition normally indicate that: MAD is binding to CDC20; • Ubiquitin is not attached to securin; • Sister chromatids separate and move to opposite poles of the cell. Which of the following explanations could account for all of your observations? a. The cell has an alteration in MAD that prevents it from releasing CDC20 when the 'unattached kinetochore' signal stops. O b. More than one of the other answer choices are correct.…
Which statement about the daughter cells of mitosis is correct? O A. They are genetically identical to one another and to the parent cell. O B. They are derived from the polar bodies during cell divison O C. They are genetically identical to one another but are different from the parent cell. O D. They differ genetically from one another and from the parent cell O E. Only one of the two daughter cells is genetically identical to the parent cell. A Moving to another question will save this response.

In general, are somatic cells genetically identical? Why or why not? Group of answer choices 1. yes - they come from meiosis 2. no - they come from mitosis 3. yes - they come from mitosis 4. no - they come from meiosis
Cell division cycle mutations render the mutants unable to continue the cell cycle. This phenotype creates a paradox where mutant cells must also be grown in the lab to further identify the gene and study the role of the protein. How do you think this problem can be solved?
Imagine that a cell contains a temperature-sensitive mutation such that nuclear lamins cannot be phosphorylated at the restrictive temperature. Describe the phenotype of the mutant cells during mitosis at the restrictive temperature. O The mutant cells will not be able to decondense chromosomes and will be arrested in prophase O The mutant cells will not be able to assemble the mitotic spindle and will be arrested in metaphase O The mutant cells will not be able to disassemble the nuclear envelope and will be arrested in prophase The mutant cells will go through multiple mitotic cycles without cytokinesis and will become multi-nucleated The mutant cells will be unable to reassemble the nuclear envelope and will be arrested in telophase
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. Imagine I have just induced a mutation in a cell line which prevents the breakdown of the cyclin molecule we discussed. 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 active
