Explanation / Answer

axoneme microtubule: ans (P) - is in cilia and flagella.

nucleation: ans (C) nucleates the microtubule brances.

gelsolin: ans (F)- assembly and disassembly on opposite ends of same filaments.

desmin: ans (G) desmosome

ARP 2/3 complex structure : ans (S) nucleates actin filament brances

myosin subfragment 1 (S1): ans (N) decorates actin microfilaments.

EB1: ans (M) binds to the microtubule plus ends

tropomodulin: ans (K) prevents loss of subunit from filament minus end

treadmilling: ans (B) stabiliozes and organizes microtubules

microvilli: ans (R) increasecell surface area

filamin: ans (U) connects crisscrossing actin filaments in to 3D networks

plectin: ans (T) crosslinks microtubule to intermediate filaments.

lamin: ans (J) forms scaffold underlying the nuclear envelope.
