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.

Cytokinesis in plant cells is different than cytokinesis in animal cells. a) Explain why it has to be different, andb) briefly describe the processes in the two different cell types.
I breed a red flower to a blue flower. What would I get if the red and blue genes in these flowers were:A) incomplete dominance B) codominance 2. What are the two purposes of the membrane?3. What is the difference between passive and active transport? 4. What kind of stem cells are pluripotent?
Which is true and which is false in the following statements: (regarding cytokinesis in animal cells)
I Fusion of vesicles with the plasma membrane provides additional surface area required for daughter cells.
II The contractile ring forms in the plane of the spindle pole body.
III The centralspindlin complex recruits a RhoA-GEF to the cell cortex overlying the midbody.
IV Local activation of formins contributes to assembly of the contractile ring.

A) CDKs promote progression of the cell cycle, cyclins function to inhibit progression of the cell cycle B) CDKs are the checkpoints in the cell cycle, and when bound to cyclins, they stop progression of the cell cycle C) CDKs will only work to promote progression of the cell cycle when complexed with their designated cyclins D) CDKs are rarely expressed during a cell's cycle, unless cyclins are present to act as transcription factors .arrow_forward

Select one: a. All the answers are correct and needed to progress the cell past the G1 checkpoint by expressing the enzymes necessary for DNA replication. Once these proteins are all expressed, the cell has moved past G1 into S phase. b. Primase because this enzyme is needed for DNA replication moving the cell from G1 to S. c. Cyclins because the accumulation of specific cyclins will turn on CDKs needed to turn on gene expression for proteins involved in DNA replication, moving the cell from G1 to S. d. DNA helicase because this protein is needed for DNA replication (part of S phase). So expression will help progress the cell from G1 to S.arrow_forwardProgression through the cell cycle is dependent on both extra- and intracellular conditions. Consider the following conditions.
