Question

Describe the role of the following structures or proteins in cell division:

cohesin protein

Accepted Answer

Welcome back, everyone. Let's look at our next question. It says which of the following proteins is responsible for stabilizing microtubules during cell division. The answer choices are a tubulin B, kinetic C Acton or D flagellant. Well, we can first eliminate right off the bat kinetic core because kinetic core is not a single protein. The kinetic core is a protein complex that attaches the microtubules to the chromosomes. So we can eliminate that as we are looking for a protein. And the answer we're going to want is choice. A tubulin tubulin makes up the microtubules and the tubulin subunits are long stable filaments. They can rapidly delirate depolymerize to allow dynamic changes in microbial structure and function. So they can actually disassemble and reassemble, allowing this very rapid um change in their structure and their function in directing cell division. Let's just look at our other answer choices to understand why they're not correct choice. C Acton Acton is a cytoskeleton component. It plays an important role in regulating cell division and organelles travel along acting filaments during cytokinesis. And it's also part of the contractile ring that divides the two cells during cytokinesis. But it's not what stabilizes microtubules. So it's not our answer. And finally choice, the flagella is what forms the filament in bacterial flagella. So it's a filament like tubulin but not the one we're looking for. So we can cross that out as well. So again, which of the following proteins is responsible for stabilizing microtubules, string cell division choice a tubulin. See you in the next video.
