WebbIn most animal cells, the microtubules are organized around an organelle called a centrosome. One centrosome is present at each spindle pole. A centrosome consists of two centrioles surrounded by a shapeless mass of proteins called the pericentriolar matrix. The centrosome produces, organizes, and anchors microtubules in the cell.

The spindle grows between the centrosomes as they move apart. The nucleolus (or nucleoli, plural), a part of the nucleus where ribosomes are made, disappears. simon peters plumbing and heatingThe cellular spindle apparatus includes the spindle microtubules, associated proteins, which include kinesin and dynein molecular motors, condensed chromosomes, and any centrosomes or asters that may be present at the spindle poles depending on the cell type. The spindle apparatus is vaguely ellipsoid in cross Visa mer In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, … Visa mer Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor spindle formation and prevent premature Visa mer The guanine nucleotide exchange factor for the small GTPase Ran (Regulator of chromosome condensation 1 or RCC1) is attached to nucleosomes via core histones H2A and … Visa mer By the end of DNA replication, sister chromatids are bound together in an amorphous mass of tangled DNA and protein.
