The weight, height, inner-hole diameter, and total diameter of each spindle whorl were measured.
Another important role for microtubules is in cell division, where they make up the spindle fibres.
At first sight, this may indicate a role for the 'elimination chromatin' in the organisation of the second meiotic spindle.
Therefore, during spindle recovery chromosomes may be rearranged on the spindle and mistakes in the segregation between microtubules and chromosomes may occur.
The floating bearing was assumed not to affect the error motions of the spindle assembly and was not included in the machine model.
At this early stage the mitotic spindle is located some 50 m from the top of the blastodisc.
It was of interest to us to examine whether inhibition of calmodulin would affect spindle formation and/or chromatin condensation and alignment.
This cycle waxes and wanes at variable intervals; between spindles, thalamocortical neurons are depolarized.
