The drug cytochalasin targets actin filaments in the cytoskeleton, preventing them from forming. Treatment of a cell with cytochalasin would result in its inability to . Multiple Choice prevent mutations in its chromosome form cellular extensions form the nuclear envelope structure transport substances within the cell

Explanation:

Actin filaments are linear chain of globular actin (G-actin) subunits.

Actin filaments occur as microfilaments in the cytoskeleton inside the cell membrane, which are part of the contractile apparatus in muscle and non-muscle cells and various other type of cells.

Actin filaments are particularly abundant beneath the plasma membrane, they form a network that provides mechanical support, they determines cell shape,  enabling cells to migrate, engulf particles, and divide.

well we can't tell you because we cant see the time give a screen shot or something.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
