Multiple Choice QuestionsIn cell cycle, during which phase chromosomes are arranged in equatorial plate?
Metaphase
Anaphase
Telophase
Prophase
A.
Metaphase
Metaphase in both mitosis and meiosis is characterized by the arrangement of chromosomes on the spindle fibres at the equatorial plate.
Prophase is the longest phase. In this phase, chromatin of nucleus becomes condensed forming chromosomes.
Anaphase is the phase where the separation of chromatids takes place. It moves in the opposite direction towards the pole and is the shortest phase of all.
Telophase is the last phase. In this phase, chromatin network are reformed, nuclear membrane and nucleolus reappears.
