What is the mitotic spindle simple?

What is a mitotic spindle?

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.

What is a spindle and its function?

The spindle fibers provide a framework and means of attachment that keep chromosomes organized, aligned and assorted during the entire process of mitosis, lessening the occurrence of aneuploidy, or daughter cells with incomplete sets of chromosomes.

What is the mitotic spindle and what is it made of?

The mitotic spindle is a highly dynamic molecular machine composed of tubulin, motors, and other molecules. It assembles around the chromosomes and distributes the duplicated genome to the daughter cells during mitosis.

What is mitotic spindle quizlet?

Mitotic spindle. An assemblage of microtubules and associated proteins that is involved in the movements of chromosomes during mitosis.

What is a spindle what is its function quizlet?

Spindle. Definition: Fan-like structure made of microtubules that helps separate the chromosomes during mitosis.

What is the function of spindle in lathe machine?

Lathe spindles are used for machine-cutting of workpieces. They can also be referred to as workpiece spindles, as the workpiece is clamped via the chuck of the lathe spindle. The rotating workpiece is machined by the tool attached to the driven machine axis.

What is the role of the spindle in mitosis quizlet?

During mitosis, the spindle fibers are called the mitotic spindle. … Their proteins help to hold the sister chromatids together and also play a role in chromosome editing.is a protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart.

What is the primary function of the mitotic spindle?

The mitotic spindle apparatus serves to pull duplicated chromosomes apart.

What is the role of spindle apparatus in mitosis?

Microtubules form the mitotic apparatus (mitotic spindle) whose main function is to separate chromosomes to the newly dividing cells (Fig. 5). These microtubules are organized from centrosomes (microtubule organizing centers; MTOCs) at the two opposite mitotic poles.
