Microtubules within a cell appear to be arranged in specific arrays. What cellular structure is responsible for determining the arrangement of microtubules within a cell? How many of these structures are found in a typical cell? Describe how such structures serve to nucleate microtubule assembly.
Taxol is a drug that inhibits microtubule dynamics and is often used for cancer chemotherapy because it preferentially affects dividing cells. What microtubule-based structure is likely disrupted by Taxol so that it specifically affects proliferating cells?
Certain cellular components appear to move bidirectionally on microtubules. Describe how this is possible given that microtubule orientation is fixed by the MTOC.
Cell motility has been described as being like the motion of tank treads. At the leading edge, actin filaments form rapidly into bundles and networks that make protrusions and move the cell forward. At the rear, cell adhesions are broken and the tail end of the cell is brought forward. What provides the traction for moving cells? How does cell-body translocation happen? How are cell adhesions released as cells move forward?
The lifetime of a microtubule in a mammalian cell, between its formation by polymerization and its spontaneous disappearance by depolymerization, varies with the stage of the cell cycle. For an actively proliferating cell, the average lifetime is 5 minutes in interphase and 15 seconds in mitosis. If the average length of a microtubule in interphase is 20 μm, how long will it be during mitosis, assuming that the rates of microtubule elongation due to the addition of tubulin subunits in the two phases are the same?
Question 11 Which of the following statements is true regarding pili and flagella assembly? O Pili and flagella are synthesized in a similar fashion; the proteins are produced internally then added to the base of the growing appendage. O Pili and flagella are synthesized in a similar, complex manner, approximately 20 different proteins are made inside the cell then secreted to extend the tip of the appendage. O Pili grow when protein subunits are added to the base, whereas flagellin proteins are added to the tip of the flagella during growth. O Pili grow when protein subunits are added to the tip, whereas flagellin proteins are added to the base of the flagella during growth.
In all cells, microtubules nucleate from the centrosome and then become stabilized or collapse. What feature of microtubules contributes to this phenomenon?
What are the key differences between rough endoplasmic reticulum and smooth endoplasmic reticulum. It would be very helpful if its in tabular form. Please help me. Thank you
A patient has ingested a chemical known to prevent alpha-tubulin from hydrolyzing GTP to GDP. Which of the following is the BEST conclusion? O The patient's dyneins and kinesins will not be able to hydrolyze nucleotides. O The patient's microtubules will only be able to grow. O The patient's microtubules should still be able to grow and shrink depending on the needs of the cell. O The patient's microtubules will only be able to shrink.
Some drugs can prevent the formation of new lysosomes. However, a cell would continue to make hydrolytic enzymes from the DNA still contained in the cell. Where would you most likely find these enzymes after the drug treatment? O Golgi Complex O Smooth Endoplasmic Reticulum O Nucleus O Mitochondrion Strikingly different signaling systems can operate in similar ways. For example, ethylene gas released by ripening fruits diffuses through the air from plant to
Microtubules, composed of a-tubulin and b-tubulin subunits, are required for all of the following eukaryotic cell movements except: axonal transport of vesicles in neurons movement of eukaryotic cilia movement of chromosomes during mitosis movement of eukaryotic flagella extension of a pseudopod during phagocytosis
Dynamic instability is the phenomenon by which microtubules undergo rapid growth and disassembly. Which of the following is true? The GTP cap provides stability to the microtubule Taxol is responsible for the depolarization of protofilaments. GTP hydrolysis is responsible for the continued growth of a protofilament. Beta-tubulin is responsible for ensuring that GTP is not hydrolyzed to GDP.
