Where are the chromosomes located during metaphase?
Options
- AAttached to the centromeres
- BAligned along the metaphase plate at the spindle equator
- CConnected to spindle fibres from one pole
- DDisintegrated in the cytoplasm
Correct answer
B. Aligned along the metaphase plate 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 plane of alignment of the chromosomes at metaphase is referred to as the metaphase plate. The key features of metaphase are: Spindle fibres attach to kinetochores ofchromosomes. Chromosomes are moved to spindle equator and get alig
