Question

A diploid cell becomes tetraploid in .............. phase.

• A. G${}_2$
• B. Prophase
• C. Metaphase
• D. Anaphase

Answer 1

The correct option is D Anaphase

Mitosis is an equational division. Anaphase is the stage when a diploid cell becomes tetraploid in mitosis. During anaphase, the cohesins that bind sister chromatids together are cleaved, forming two identical daughter chromosomes. Shortening of the kinetochore microtubules pulls the newly formed daughter chromosomes to opposite ends of the cell.

So, the correct answer is option D.
