Tubulin dimers with nucleoside diphosphates in their nucleotide binding site(s)

Question

Tubulin dimers with nucleoside diphosphates in their nucleotide binding site(s) have a lower affinity for each other than tubulin dimers with nucleoside triphosphates in their nucleotide binding site(s).
Only the alpha subunit of a tubulin dimer has a nucleotide binding site.
Myosin is a motor protein that moves toward the plus end of microtubules.
In vivo, polymerization of microtubules typically occurs at the minus end because the plus end is anchored.
ATP is the nucleotide that occupies the nucleotide binding site(s) of tubulin dimers.

Explanation / Answer

The alpha and beta tubulins represent the major components of microtubules, while gamma tubulin plays a critical role in the nucleation of microtubule assembly.

The protofilaments bundle parallel to one another, so in a microtubule, there is ... eukaryotic cells to segregate their chromosomes correctly during cell division

Only the alpha subunit of a tubulin dimer has a nucleotide binding site.
Myosin is a motor protein that moves toward the plus end of microtubules.
