a. have a diameter of 7 nm and contain 375 amino acids
b. are composed of 2 subunits each of molecular weight of 42 kDa
c. have a diameter of 7 nm and contain 450 amino acids
d. have no polarity
e. have GTP in each of the monomers
f. None of the above - None of the above
1. Actin filaments will ____________.
a. undergo treadmilling in a test tube
b. undergo treadmilling in a living cell
c. never reach equilibrium
d. Two of the above
e. None of the above
f. I don't know the answer - d. Two of the above
1. Actin filaments associate with a nucleotide triphosphate.
a. True
b. False - True
1. Treadmilling of actin filaments only occurs in a test tube.
a. True
b. False - False
The number of amino acids in an actin monomer is:
375
450
460 -780
750 - 375
Hydrolysis of ATP to ADP:
, helps identify the assembly vs the disassembly end
is used in dynamic instability
has a role when the actin filament is in chemical equilibrium with the actin
filament monomers
is important for the nucleation site - helps identify the assembly vs the disassembly
end
Actin filaments associate with a nucleotide triphosphate. t/f - True
Treadmilling of actin filaments only occurs in a test tube. T/F - false
Preassembled nucleaton sites in a living cell are equivalent to the intracellular
preference for actin filaments. T/F - True (pre-assembled nucleation sites creates a
subcellular location from which actin filaments can elongate.)
Intracellular preference for actin filaments :
is a way to look a the geography of the cell and the role of the nucleus.
is a way to look at the geography of the cell and show where the role of actin
filaments is important.
explain how actin gets into the nucleus.
explain how the Golgi Apparatus forms.
two of the above. - is a way to look at the geography of the cell and show where
the role of actin filaments is important.
The ability of actin filaments to disassemble into small monomers:
