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 function of the spindle What are the structural components of the spindle?
In cells that have a nucleus, a structure called the mitotic spindle ensures that chromosomes are partitioned equally between the dividing cells. The spindle consists of long, thin protein fibers called microtubules, which grow from small structures known as centrosomes that are present on either side of a cell.
What is the structure and function of the 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 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 mitotic spindle quizlet?
Mitotic spindle. An assemblage of microtubules and associated proteins that is involved in the movements of chromosomes during mitosis.
