What is the purpose of the metaphase stage in mitosis?
Options
- ATo separate the chromatids
- BTo align the chromosomes at the spindle equator
- CTo move the chromosomes to opposite poles of the cell
- DTo initiate the condensation of chromosomal material
Correct answer
B. To align the chromosomes at the spindle equator
Step-by-step solution
Hence, 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. The key features of metaphase are: Spindle fibres attach to kinetochores ofchromosomes. Chromosomes are moved to spindle equator and get aligned along metaphase plate through spindle fibres to both poles.
