In the cell, microtubule organizing centers (MTOCs) dynamically nucleate microtubules and arrange them in functional patterns, but microtubule anchoring to MTOCs is not well understood. A novel ...

Researchers have identified a novel protein that plays a crucial role in the formation of the mitotic spindle, which is essential for correct segregation of a full set of chromosomes to each daughter ...

Cambridge, Mass. - April 26, 2012 - The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to ...

Abnormalities in the spindles (the bi-polar thread like structures that link and pull the chromosomes during cell division) of human embryos before implantation may be the primary reason for many of ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic material (chromosomes) equally, and then rebuild the nuclear envelope around ...

American Journal of Botany, Vol. 28, No. 8 (Oct., 1941), pp. 713-722 (10 pages) The first microspore division in many seed plants differs from the usual type of mitosis in that: (1) the prophase ...

New cells are formed during cell division by a precisely regulated partitioning of cellular content into the two daughter cells. Cell division is therefore a fundamental biological process in which ...
