Cytochalasins bind actin and block actin microfilament assembly. cells treated with cytochalasins will not divide. how do cytochalasins block cell division?
ocytochalasins prevent the contractile ring from forming and dividing the cell in two.
o cytochalasins prevents dna replication.
o cytochalasins prevents separation of chromatids by the spindle.
o cytochalasins prevents chromosome condensation during prophase

The correct answer will be option-A

Explanation:

Cytochalasin is the metabolic product released from the fungus. The cytochalasin acts a toxin to the cell as it inhibits the division of the cell.

Cytochalasin act by inhibiting the cytoplasmic separation during cell division as it blocks the formation of contractile microfilaments. The presence of cytochalasin inhibits the elongation of acing filament as it blocks the addition of the monomer to the growing end of the filament.

Since it prevents the formation of the contractile rings and cytoplasmic separation, therefore, option-A is the correct answer.
