What is the mitotic spindle and what role does it play in mitosis?

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 the Role of mitotic spindle in mitosis?

The mitotic spindle is the macromolecular machine that segregates chromosomes to two daughter cells during mitosis.

What is the role of the mitotic spindle and what is it composed 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. … Then soluble and chromosome-associated molecular motors sort them into a bipolar array.

What is the mitotic spindle quizlet?

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

What is the mitotic spindle and when does it occur?

The mitotic spindle is a structure that forms during cell division and separates duplicated chromosomes. In eukaryotic cells, the mitotic apparatus is composed of two centrosomes and spindle microtubules (Figure 43.9).

What role does spindle play in the dividing cell?

Each spindle fiber is formed from several microtubules. The spindle fibers act like small machines during cell division. They carefully assemble and divide the chromosomes, and have been doing so for billions of years.

IT IS SURPRISING:  What role do mitosis and meiosis play in the development of an organism?

What is the mitotic spindle called?

The spindle apparatus that forms during mitosis is referred to as mitotic spindle whereas the one that forms during meiosis is called meiotic spindle. Spindle fibers are made up of microtubules and they appear as spindle-shaped structures (thus, the name). They develop outside the nucleus during mitosis.
