 | Cells stabilize their machinery for forcing apart chromosomes in an amazingly simple way. Attachments between the microtubules that tug apart the chromosomes and the connector on the chromosomes become more stable when they are placed under tension. This tension occurs when the microtubles are properly aligned on either side of the paired chromosomes. If the alignment is incorrect, the tension is weak, and the attachment is released and fixed. This stabilization method assures accurate separation of chromosomes. ...> Full Article |
 | Whitehead Institute researchers have determined how cells regulate the chromosome/microtubule interface, which is central to proper chromosomal distribution during cell division. The chromosome/microtubule interface is critical during cell division. If a microtubule attaches incorrectly to a chromosome and cell division proceeds, the chromosomes may divide unevenly, resulting in cells with an incorrect number of chromosomes. Aberrant distribution of chromosomes can lead to cancer or premature cell death. ...> Full Article |
Chromosomes move faster than we first thought. Research published in BioMed Central's open access journal, Genome Biology, details new findings about the way chromosomes move around the nucleus when leaving the proliferative stage of the cell cycle and entering quiescence -- and the unexpected speed at which they move.
