What does the mitotic spindle do during mitosis quizlet?

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 does the mitotic spindle do for the cell during 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 mitotic spindle involved in quizlet?

The mitotic spindle is responsible for separating the replicated chromosomes and allocating one copy of each chromosome to each daughter cell.

What is the role of the spindle during mitosis answers?

Answer Expert Verified

Spindle fibers attach to chromosomes and pull them towards different poles of the cell during the final phases of mitosis. The result is two identical cells with the same chromosomes. A cell plate is a structure found in plant cells on the top and bottom of the cell.

What makes up the mitotic spindle?

The mitotic spindle is the microtubule-based bipolar structure that segregates the chromosomes in mitosis. The poles of the mitotic spindle are made up of centrosomes and the chromosomes are lined up at the spindle equator to ensure their correct bi-orientation and segregation.

How does the mitotic spindle develop quizlet?

The mitotic spindle begins to form in the cytoplasm during prophase. It consists of fibers made of microtubules and associated proteins. … Then, during prophase each duplicated chromosome appears as two identical sister chromatids joined at their centromeres and, in some species, all along their arms by cohesion.

What pivotal role does the mitotic spindle play in cell division?

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 would happen if spindle fibers don’t form during mitosis?

Spindle fiber formation occurs but spindle fibers cannot function properly, i.e. they cannot separate the daughter chromosomes in the division process. … Chromosomes clump in several areas of the cell rather than along the single metaphase plate. Mitosis is disrupted and growth increases.

What is the result of preventing spindle fibers from forming?

Colchicine prevents spindle fibers from forming during the cell cycle. What is a result of preventing spindle fibers from forming? … Mitotic division is skipped, and the cell cycle proceeds to cytokinesis. Mitotic division stops in metaphase and cannot proceed to anaphase.

What is the end result of mitosis and cytokinesis Why is this so important?

The end result of mitosis and cytokinesis is two new cells that are identical to the original mother cell. It is important that the new cells be able to carry out the same function as the mother cell. … The cell would be divided into two cells. One cell would have a nucleus and chromosomes, and the other cell would not.
