Textbook Question
Chapter 10, Problem 6A
In animal cells, cytokinesis is accomplished by a contractile ring containing actin. The related process in bacteria is
a. chromosome segregation, which also appears to use an actinlike protein.
b. septation via a ring of FtsZ protein, which is an actinlike protein.
c. cytokinesis, which requires formation of a cell plate via vesicular fusion.
d. septation via a ring of FtsZ protein, which is a tubulin-like protein.

Which of the following are stages in the cytokinesis of animal cells? Select all that apply.
A) The cell plate expands along the plane of division, and when the plate fuses with the plasma membrane, the cytoplasm is partitioned into two new cells.
B)After telophase, the contractile ring constricts the plasma membrane and forms a cleavage furrow.
C)The contractile ring reaches its smallest diameter, and the spindle microtubules are cut as vesicles form the new membranes that separate the two new cells.
D)A contractile ring of microfilaments and motor proteins forms under the plasma membrane during anaphase.

- You genetically engineered a cell to no longer contain the extracellular domain of an integrin. What is the most likely effect of losing this domain on the cell's ability to bind? A It would affect the cell's ability to attach to the ECM. B It would have no effect on the cell's ability to attach to anything. C It would affect the cell's ability to attach to the cytoskeleton through adaptor proteins. D It would affect both the cell's ability to attach to other cells and the cell's ability to attach to the cytoskeleton.arrow_forwardWhich of the following statements is true regarding cell cycle regulators? a. Cyclins determine which proteins each Cdks will act on. b. Cdks check the DNA for damage and repairs it. c. Cyclin binding to Cdks will result to Cdk inactivation. d. Cyclin levels remain constant through the cell cycle.arrow_forwardWhich of the following statements about the cell cycle is TRUE? a. The protein APC blocks cells from entering anaphase b. CDKs are degraded after each cell cycle phase by the addition of a ubiquitin chain to the proteins c. A kinase is a protein that adds a ubiquitin chain to other proteins Cyclin activity is necessary, but not always sufficient, for CDK activation d.

- Describe the similarities and differences between the cytokinesis mechanisms found in animal cells vs those in plant cellsarrow_forwardIn addition to phagocytosis, neutrophils use a process called NETs. Which one of the following describes this process? A. NETs is a neutrophil process that activates the complement system of proteins, which destroys pathogens. B. NETs are chemicals secreted by neutrophils that trigger the rapid maturation of lymphoid stem cells into lymphocytes. C. A net-like structure of DNA, histones, lactoferrins, gelatinase, cathepsin G, and myeloperoxidase is secreted at pathogens. Together these chemicals destroy pathogens. D. NETs works when neutrophils secrete major basic proteins onto pathogens, destroying the pathogens' cell membranes.arrow_forwardWhich of the following is not true regarding cytokinesis?* A.Simultaneously happen with the telophase.
