How long does cooked salmon last in the freezer? Properly stored, it will maintain best quality for about 2 to 3 months, but will remain safe beyond that time. The freezer time shown is for best quality only - cooked salmon that has been kept constantly frozen at 0Â°F will keep safe indefinitely.
Mitotic spindle. Definition. noun. The collective term for all the spindle fibers that form during mitosis. It is a spindle-shaped structure that develops outside the nucleus during mitosis. The fibers that constitute the mitotic spindle pull the chromatids apart toward opposite poles. Supplement.
Definition: Spindle fibers are aggregates of microtubules that move chromosomes during cell division. During prophase of mitosis, spindle fibers form at opposite poles of the cell. During metaphase, spindle fibers extend from the cell poles toward the midpoint of the cell known as the metaphase plate. Chromosomes are held at the metaphase plate by the equal forces of the spindle fibers pushing on the centromeres of the chromosomes. In anaphase, spindle fibers pull sister chromatids toward the spindle poles. Spindle fibers not connected to chromatids lengthen and elongate the cell.
