Which of the following statements is not correct regarding colchicine?

Options

A. It prevents assembly of microtubules.
B. It inhibits chromosome replication.
C. It is an alkaloid.
D. It is called as mitotic poison.

Answer

B

Explanation

Colchicine is an alkaloid widely used in plant breeding for doubling the chromosome number. The alkaloid does not allow the formation of spindle because it prevetns assembly of microtubules. It is, therefore, called 'mitotic poison'. Colchicine holds holds the cells in metaphase. Colchicine does not inhibit chromosome replication.
