| 21. | Required for chromosome segregation at metaphase-anaphase transition, robust mitotic spindle formation and cytokinesis.
|
| 22. | Mitotic metaphase chromosomes are best described by a linearly organized longitudinally compressed array of consecutive chromatin loops.
|
| 23. | M cyclin concentrations rise as the cell begins to enter mitosis and the concentrations peak at metaphase.
|
| 24. | Cdc2, part of the metaphase entry checkpoint, is active depending on the pattern of phosphorylation.
|
| 25. | Overexpression of cyclin A2 in mammalian cells can result in the delayed onset of metaphase and anaphase.
|
| 26. | During metaphase, they appear merely as 0.5-1.5 ?m long specks.
|
| 27. | The key to their success was utilizing oocytes in metaphase II ( MII ) of the cell cycle.
|
| 28. | Micrograph showing condensed chromosomes in blue, kinetochores in pink, and microtubules in green during metaphase of mitosis
|
| 29. | But when it comes to metaphase 2-do the chromosomes line up randomly again before they split?
|
| 30. | Researchers have detached grasshopper spermatocytes from spindle fibers and moved them away from the metaphase plate via micromanipulation.
