Definition of mitotic spindle easy Spindle fibers are microscopic protein structures that help divide genetic material during cell division and organize cellular components. The spindle fibers form out of the centrosome, also known as the microtubule-organizing center, or MTOC. Spindle fibers are formed from microtubules with many

During mitosis, the spindle fibers are called the mitotic spindle. Meanwhile, during meiosis, the spindle fibers are referred to as the meiotic spindle. At the 

phase spindles recovered rapidly as the detached pole moved back towards the chromosomes, reestablishing spindle fibers as the ARB closed; this happened when the ARB cut a few fibers or across the entire half spindle. We never detected elongation of the cut kinetochore fibers. Spindle microtubules are assembled from opposite spindle poles and a fraction of them are organized to form thick bundles of spindle fibers (k‐fibers) during prophase till prometaphase. At prometaphase, the k‐fibers are yet to establish attachment with the kinetochores of both sister chromatids of the individual chromosomes (biorientation). This preview shows page 2 - 3 out of 3 pages.. a) The _____ spindle fibers _____ and _____ the attached sister chromatids apart at the _____ towards opposite poles.

The polar axis of the mitotic apparatus was rotated to a point 45• with respect to the polarizer-analyzer axis, the immediate background was brought to extinction, the spindle fibers were brought to extinction (but not to maximum contrast), and the difference in compensator angles Define mitotic spindle. mitotic spindle synonyms, mitotic spindle pronunciation, mitotic spindle translation, English dictionary definition of mitotic spindle. n. One of a network of achromatic filaments that extend inward from the poles of a dividing cell, forming a spindle-shaped figure. phase spindles recovered rapidly as the detached pole moved back towards the chromosomes, reestablishing spindle fibers as the ARB closed; this happened when the ARB cut a few fibers or across the entire half spindle. We never detected elongation of the cut kinetochore fibers. Spindle microtubules are assembled from opposite spindle poles and a fraction of them are organized to form thick bundles of spindle fibers (k‐fibers) during prophase till prometaphase.

In the classic view of the spindle, the kinetochore microtubules (k-fibers) are tensed and, thus, straight, whereas interpolar Definition of mitotic spindle easy Spindle fibers are microscopic protein structures that help divide genetic material during cell division and organize cellular components.

In retrospect, that is not so surprising because the fibers ofthe spindle andaster are immersedin (and spun outfrom)thehyaline cytoplasm that permeatesthe cell. Large cytoplasmic granules are excludedfromthe spindle, but ribo-somesandsome membranesare not. Yolkandother granules spindle fiber structure a protein structure that partitions the hereditary material in a cell.

that kinetochore fibers (K-fibers) in plant cells are con- nected to the spindle pole [Lambert et al., 19911, an entity which to our knowledge has never been studied in detail and has not yet been defined. Clearly, an evalua- tion of the spindle polar region in higher plants is needed.
