What does the mitotic spindle do quizlet?

What does the mitotic spindle do?

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 what is its function quizlet?

Spindle. Definition: Fan-like structure made of microtubules that helps separate the chromosomes 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 does the mitotic spindle become?

The mitotic spindles are depolymerized into tubulin monomers that will be used to assemble cytoskeletal components for each daughter cell.

What major role do spindle fibers play in cell division?

Spindle fibers are filaments that form the mitotic spindle in cell division, i.e. mitosis and meiosis. They are chiefly involved in moving and segregating the chromosomes during nuclear division. Spindle fibers are made up of microtubules.

What is the role of the spindle fibers during mitosis group of answer choices?

What is the most significant role of the spindle fibers during mitosis? The spindle fibers help separate the chromosomes.

What functions do centrosomes have during mitosis?

Centrosomes assist with several important functions, including: Organizing changes to the shape of the cell membrane that allow the membrane to “pinch” in two during cell division. Ensuring that chromosomes are properly distributed to daughter cells by creating and shortening mitotic spindle fibers.

What does mitotic spindle fibers mean?

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.

What are the functions of mitotic apparatus?

a temporary structure in a dividing cell that enables the chromosomes to move to the poles of the cell, thus ensuring their even distribution between the daughter cells.
