Created by StemPy LabA dividing cell is seen with its chromosomes moving to opposite poles. Each moving chromosome still has two chromatids joined at its centromere. Which stage is this?
← All Quizzes
← Assertion (A): Metaphase is the stage at which the morphology of chromosomes is most easily studied.
Reason (R): By metaphase, the condensation of the chromosomes is complete, and they can be observed clearly under the microscope.Read the following statements about a cell at the end of prophase of mitosis.
(i) The chromosomal material has condensed to form compact mitotic chromosomes.
(ii) Each chromosome is seen to be made of two chromatids attached together at the centromere.
(iii) The centrosome duplicated during interphase, and the two centrosomes have begun to move towards opposite poles of the cell.
(iv) Golgi complexes, endoplasmic reticulum, nucleolus and the nuclear envelope are not seen.
(v) The chromosomes are aligned on the metaphase plate.
(vi) The centromeres have split, and the sister chromatids have separated.
