Question

Cytochalasin B is a chemical that disrupts microfilament formation. This chemical would interfere with
a. DNA replication.
b. formation of the mitotic spindle.
c. cleavage.
d. formation of the cell plate.

Accepted Answer

Welcome back. Here's our next question. The micro trivial targeting agents are successful cancer treatment drugs that interfere with blank. Well, as you can kind of guess by the name here, we know that the micro tubules are part of the assembly of the main topic spindle. So when you target these agents with a drug, the drug interferes with that process of forming the spindle and that works as an anti cancer treatment. Because uh the cell then gets halted at meta phase in mitosis. Uh There's a checkpoint and meta phase where the cell waits until all chroma tides are correctly attached to the micro tubules of the spindle and it will not progress to anNA phase until that happens. So when that process interfered with by targeting the micro tubules, then the cell is stuck at the checkpoint and after an extended period of time being stuck at that checkpoint that can lead to apoptosis or programmed cell death. So you target those microchip vehicles and you end up killing the cancer cell. So when we look at our answer choices, we have choice a kinetic or formation um That looks plausible because kinetic or is that structure on the chroma tied? That the micro the spindle attaches to. But the targeting agents target the micro tubules themselves, not the kinetic core. So that's not our answer. Choice B is my topic spindle dynamics. That is our correct answer. The micro tubules are what make up that my topic spindle. So drugs that target them affect the formation the dynamics of that topic. Spindle choice C. Says poly a tail capping. Um That's the process that puts a poly a tail on the end of a newly synthesized M. RNA molecule protecting it from degradation. So not what these cancer drugs are involved in. So not our answer. And finally, Choice D. Says DNA synthesis. Again, these micro trivial targeting agents do not affect the DNA synthesis stage, so not our answer. So again the microbial targeting agents interfere with choice be made topic. Spindle dynamics. See you in the next video.
