A study in the journal Science is offering new insights into a long-standing mystery about plant growth. The scientists who conducted the experiment say their results could open new avenues of ...

Researchers at the Centre for Genomic Regulation (CRG) have discovered how proteins work in tandem to regulate ‘treadmilling’, a mechanism used by the network of microtubules inside cells to ensure ...

(a) Ostergren's view in the late 1940s. The image represents the spindle in an insect spermatocyte. The forces acting on the chromosomes (arrows) were inferred from chromosome stretching and ...

Researchers at the Centre for Genomic Regulation (CRG) have discovered how proteins work in tandem to regulate 'treadmilling', a mechanism used by the network of microtubules inside cells to ensure ...

Using an immunoelectron microscopic procedure, we directly observed the concurrent addition and loss of chicken brain tubulin subunits from the opposite ends of microtubules containing erythrocyte ...

One recent hypothesis for the mechanism of chromosome movement during mitosis predicts that a continual, uniform, poleward flow or "treadmilling" of microtubules occurs within the half-spindle between ...

In most animal cells, microtubules are focused on the centrosome, an organelle near the nucleus that organizes the microtubule cytoskeleton into a radial array. As a result, they exhibit a property ...

Researchers have discovered how proteins work in tandem to regulate 'treadmilling', a mechanism used by the network of microtubules inside cells to ensure proper cell division. Researchers at the ...
