Question

Select the incorrect statement with reference to mitosis:

• A. All the chromosomes lie at the equator at metaphase
• B. Spindle fibres attach to centromere of chromosomes
• C. Chromosomes decondense at the telophase stage
• D. Splitting of centromere occurs at anaphase

Answer 1

Answer: (B)

Spindle fibres attach to centromere of chromosomes

Answer 2

The correct answer is (b).
In mitosis, the metaphase is characterised by all the chromosomes coming to lie at the equator with one chromatid of each chromosome connected by its kinetochore to spindle fibres from one pole and its sister chromatid connected by its kinetochore to spindle fibres from the opposite pole.
