As a result of testing an experimental drip on a vertebrate cell, you notice that the cell cortex becomes more fluid, and although the cell remains strong, it loses its ability to move. Based on this evidence, you correctly conclude that the drug most directly affected:
A) myosin.
B) β -tubulin.
C) α -tubulin.
D) actin filaments.
E) intermediate filaments.
