Q. 12 - Biology

Question

Separation of the sister chromatids is a characteristic of which stage of mitosis? 

a. prometaphase 

b. metaphase 

c. anaphase 

d. telophase 

Step-by-Step Solution

Answer

The correct answer is C.

Step. 1 Introduction

At mitosis, an eukaryotic cell divides to become two genetically similar daughter cells by a precisely synchronized nuclear division.

Step. 2 Explanation for correct answer.

Separation of the sister chromatids and the chromosomes get driven toward opposing poles occur during anaphase.

Step. 3 Explanation for incorrect answer.

Option a. Kinetochores occur at the centromeres during prometaphase, and microtubules bind to kinetochores.

Option b. During metaphase, chromosomes align and sister chromatid becomes connected to a spindle fibre.

Option d. 

During telophase, chromosomes appear at opposing poles, and each pair of chromosomes is surrounded by fresh nuclear envelope material.
