What is the mitotic spindle involved in?
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 process is the mitotic spindle involved in during mitosis quizlet?
The mitotic spindle is the machinery that guides the separation of chromosomes in anaphase.
What is the role of the mitotic spindle 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 process is the mitotic spindle involved in during mitosis?
As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell.
What is the primary function of the mitotic spindle?
The mitotic spindle apparatus serves to pull duplicated chromosomes apart.
What is the role of the spindle during mitosis Quizizz?
Q. What is the role of the spindle during mitosis? It divides the cell in half.
During which phase of mitosis does the mitotic spindle disassemble quizlet?
-The spindle fibers disassemble during anaphase. As the spindle fibers shorten during anaphase, they separate the chromatids from one another and then move them to opposite poles.
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 mitotic spindle made of quizlet?
The mitotic spindle begins to form. The spindle is a structure made of microtubules, strong fibers that are part of the cell’s “skeleton.” Its job is to organize the chromosomes and move them around during mitosis. In prophase, the spindle grows between the centrosomes as they move apart.
What is meant by mitotic spindle?
Definition. 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.
What is mitotic spindle composed of quizlet?
What is the mitotic spindle composed of? microtubules and carious proteins that interact with the microtubules including the microtubule-associated motor proteins. The mitotic spindle is responsible for separating the replicated chromosomes and allocating one copy of each chromosome to each daughter cell.
