During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell. The result is two genetically identical daughter nuclei. The rest of the cell may then continue to divide by cytokinesis to produce two daughter cells.

Mitotic spindle fibers

Abstract. When a cell starts to divide, it forms a spindle, a micro-machine made of microtubules, which separates the duplicated chromosomes. The attachment of microtubules to chromosomes is mediated by kinetochores, protein complexes on the chromosome. Spindle microtubules can be divided into three major classes: kinetochore microtubules, which form k-fibers ending at the kinetochore; interpolar microtubules, which extend from the opposite sides of the spindle and interact in the middle

NuMA-like pattern has associated distinct nuclear speckles. The spindle fibers are microtubules, long strands of protein that move to each side of the cell. They extend out microtubules that are used to pull the chromosomes (condensed DNA pairs) apart and The spindle fibers between the poles are stained in mitotic cells, associated with cone-shaped decoration of the mitotic poles. Spindle fibers cover both NuMA-like and non-NuMA patterns. NuMA-like pattern has associated distinct nuclear speckles. Only non-NuMA patterns are shown here while NuMA-like patterns are shown in the NuMA-like group.

Mitotic spindle fibers

When a cell starts to divide, it forms a spindle, a micro-machine made of microtubules, which separates the Introduction. Cell division is one of the most fundamental processes in the living world. At the onset of Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.

During prophase in mitosis, the chromatids begin condensing to form and the chromosomes can be pulled apart as chromatids by the spindle fibers.
