WebEvents that occur during prophase of mitosis also occur during prophase I of meiosis. The chromosomes coil up, the nuclear membrane begins to disintegrate, and the centrosomes begin moving apart. The two chromosomes may exchange fragments by a process called crossing over. When the chromosomes partially separate in late prophase, until they ... WebThree dimensional (3D) ultra-structural imaging is an important tool for unraveling the organizational structure of individual chromosomes at various stages of the cell cycle. Performing hitherto uninvestigated ultra-structural analysis of the human genome at prophase, we used serial block-face scanning electron microscopy (SBFSEM) to …

WebThe ZYP1-deficient lines analyzed in this study progress through prophase I to form COs, but in all cases progress through prophase is delayed. In the case of the T-DNA mutants there is a modest delay of 6 h, whereas in ZYP RNAi1 a substantial delay of ∼20 h is observed that appears to be due to an extension of early prophase I.
