Biology Question on cell cycle and cell division
If a diploid cell is treated with colchicine then it becomes
A
Triploid
B
Tetraploid
C
Diploid
D
Monoploid
Answer
Triploid
Explanation
Solution
The correct option is (A) : Triploid
Colchicine prevents the development of microtubules necessary for the growth of spindle fibers. To split the chromosomes in a parental cell into two daughter cells evenly, spindle fibers are required. The genetic material won't be disseminated to the two freshly growing cells if microtubules aren't produced. As a result, the metaphase stage will see a decrease in the production of new cells, and the diploid cell will divide into tetraploid cells with four chromosomes instead of two.
