Why are there motor proteins associated with both actin filaments and microtubules but not intermediate filaments? - Answer Actin filaments and microtubules are highly polarized, therefore allowing motor proteins to form associations with them. Intermediate filaments are unpolarized and do not bind nucleotides such as ATP, leading to lack of motor protein associations (which are ATP driven). How does the hydrolysis of ATP cause myosin to move along the actin filament? - Answer ATP hydroly...

Eukaryote : An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin : This shows as pale areas in the nucleas under electro magnification. It is a less densly packed form of chromatin; 10% is even l...
