What is the meaning of mitotic spindle?

What is the mitotic spindle simple?

The mitotic spindle is the macromolecular machine that segregates chromosomes to two daughter cells during mitosis. The major structural elements of the spindle are microtubule polymers, whose intrinsic polarity and dynamic properties are critical for bipolar spindle organization and function.

What forms the mitotic spindle?

The mitotic spindle is a structure that forms during cell division and separates duplicated chromosomes. … In eukaryotic cells, polymerization of microtubules from alpha and beta tubulin is initiated at the centrosome to form the mitotic spindle and the structure for cytokinesis.

What is the function of mitotic spindles in a cell?

The mitotic spindle is a structure composed of microtubules which segregates chromosomes into the daughter cells during mitosis.

What is the meaning of mitotic?

: of, relating to, involving, or occurring by cellular mitosis mitotic cell division mitotic recombination Microtubules move material through the cell and, in particular, form an important component of the mitotic spindle, which is a structure that separates the duplicated sets of chromosomes in the course of cell …

What is mitotic spindle quizlet?

What is the role of the spindle apparatus during anaphase?

During cell division, the spindle apparatus pulls together the chromosomes into the two daughter cells. … Once all the chromosomes are aligned with sister chromatids pointing to opposite ends of the spindle, the cell enters anaphase, in which the chromatids separate and move toward their respective poles.

What anchors the spindle?

During mitosis, the spindle fibers will bind to a protein complex (known as the kinetochore) at the center of the chromosome. The kinetochore serves as an anchor, allowing the spindle fibers to retract and separate the sister chromatids.

Which of the following is true of the mitotic spindle?

The correct answer is (c); it is composed of microtubules, which help separate the chromosomes to opposite poles of the cell.
