Centromere Tension Measurement in Budding Yeast Mitosis.

ABSTRACT: During budding yeast mitosis, duplicated chromosomes are aligned at the center of the metaphase mitotic spindle, and the centromeres are stretched by forces generated within the mitotic spindle. In response to these stretching forces, mechanical tension builds up in the centromeric chromatin. The magnitude of this tension is detected by the cell to signal the attachment configuration of the sister chromosomes: a high tension signal would indicate that sister chromosomes are properly attached to opposite spindle poles, while a low tension signal could indicate the lack of a bipolar attachment. A low tension signal drives the cell to correct improper attachments in metaphase, thus preventing potential errors in anaphase chromosome segregation. In this paper, we describe a microscopy-based me
