Created by StemPy LabMatch the stages of prophase I in List-I with the events in List-II. List-I (Stage) A. Zygotene B. Pachytene C. Diplotene D. Diakinesis List-II (Event) I. The chiasmata terminalise, and the nucleolus disappears II. Recombination nodules appear, and crossing over takes place III. Homologous chromosomes pair, and the synaptonemal complex forms IV. The synaptonemal complex dissolves, and X-shaped chiasmata are seen

← Two statements about interphase are given below.
Statement I: In animal cells, DNA replication begins in the nucleus during S phase, and the centriole duplicates in the cytoplasm.
Statement II: Cells that leave G1 and enter the quiescent stage (G0), such as the heart cells of adult animals, stop all their metabolic activity.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. →
