Cytochalasins bind actin and block actin microfilament assembly. Cells treated with cytochalasins will not divide. How do cytoch
alasins 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
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.
Belief doesn’t have much role in science, except in the sense that nobody can check everything. But science is a set of methods for establishing knowledge that is as good a match as possible to the world we find ourselves in.
The darker moths would be harder for the bird to see due to the amount of soot on the trees. The darker moth population would thrive and continue to grow, while the lighter colored moth population would decrease.
