Dictionary » M » Microtubule MicrotubuleMicrotubule (Science: cell biology) cytoplasmic tubule, 25nm outside diameter with a 5nm thick wall. Made of tubulin heterodimers packed in a three start helix (or of 13 protofilaments looked at another way) and associated with various other proteins (mAPs, dynein, kinesin). Microtubules of the ciliary axoneme are more permanent than cytoplasmic and spindle microtubules. ![]()

Results from our forumchromosome 2 replication.you are actually correct that there would be a problem with having two centromeres though: in metaphase a microtubule from one pole could attach to one centromere and a microtubule from the other pole would attach to the other centromere, so during anaphase in this scenario ...

How Bacteria and Viruses work.. in the Nervous system... important for the point I was trying to make above: it basically tells us that we still have a whole bunch to learn about the cytoskeleton and how microtubule position is regulated, about vesicle targeting with clathrin coat proteins and about the transport pathways within the endomembrane system.

HomeWork HELP!... It would be great if you could help me :wink: About the cell. Answer as many as you can, please. -Membrane enclosed region in a cell -A network of microtubules, microfilaments and intermediate filaments -A small membranous bag -A cluster of protein-synthesizing organelles -A water-soluble small ...

Motion of Olfactory Cilia?... of the VERY big difference in structure between olfactory cilia and "traditional" cilia. We are used to referring to cilia as that 9+2 microtubule structure, dinein and the works. However, the term cilium doesn't necessary mean that: almost all mammalian cells have a specialized structure ...

ColchicineThere are other microtubule depolymerizing drugs similar to colchicine, like nocodazole and colcemid , that bind free tubulin in a cell and prevent them from adding onto microtubules. I also know of a drug called Brefeldin that interferes ...
