What happens to a microtubule that loses its "GTP cap"?
Nothing.
It begins to assemble.
It begins to de-assemble.
Homework Answers
It begins to assemble
Microtubules are polymers of tubulin protein. They are made up of dimers of alpha and beta tubulin. These dimers repeat themselves to produce long hollow cylindrical structure which we call as microtubules.
The alpha and beta tubulin associate with each other to form microtubules polymer when GTP bound to this dimers is hydrolysed to the GDP and inorganic phosphate.
GTP is bound to the dimers in the disassembled form but when they associate with each other to assemble into microtubules, GDP is formed.

How does a GTP cap prevent a microtubule from falling apart, and how does a microtubule lose its GTP cap? If the rate of adding GTP-heterodimers to a microtubule is greater than the rate of GTP hydrolysis, then will the microtubule continue growing or fall apart? Explain your answere. Assume that in a normal cell the average length of microtubule reaches before falling apart is 8 micrometers. Imagine a cell with mutant B-tubulin that catalyzes hydrolysis at a rate slower...

Consider a mutation in tubulin that alters how tubulin changes its conformation after GTP hydrolysis. More specifically, the mutation makes tubulin "stiffer" after GTP hydrolysis, such that the tubulin does not transition as quickly between the straight and curved conformations. How would microtubule dynamics be affected by this mutation? Select all that apply. Question 5 options: a) Microtubules will grow faster (the net growth rate increases). b) Microtubules will shrink more slowly after a catastrophe (the "post-catastrophe shrinkage rate" is...

1.) What happens to the translation initiation complex before the ribosomal subunit can be added? 2.) What are two ways aminoacyl tRNA synthetase ensures proper pairing between tRNA and amino acid? 3.) What stages of transcription or translation require GTP hydrolysis? 4.) When only non-hydrolyzable GTP tubulin dimers are available, how this affect the shrinking of microtubule filament?
