What structures make up the fibers of the mitotic spindle?
The mitotic spindle is composed of microtubules, which are dynamic structures made up of tubulin protein subunits. It consists of three main types of microtubules: kinetochore microtubules that attach to the chromosomes, polar microtubules that interact with each other to help push the poles of the cell apart, and astral microtubules that anchor the spindle poles to the cell membrane.
What are spindle fibers composed of?
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
A fanlike microtubule structure that helps separate the chromosomes is a?
mitotic spindle. It is composed of microtubules and plays a crucial role in ensuring the accurate distribution of chromosomes during cell division.
What the mitotic spindle made of?
Microtubules from the cytoskeleton of the cell
How do microtubules form the mitotic spindle during cell division?
Microtubules form the mitotic spindle during cell division by organizing into a structure that helps separate chromosomes. The microtubules attach to the chromosomes and pull them apart, ensuring that each new cell receives the correct number of chromosomes.

What portion of the cell forms part of the mitotic spindle during division?
The microtubules of the cytoskeleton form the mitotic spindle during cell division, along with associated proteins. These microtubules help separate the chromosomes during mitosis.
The framework of microtubules that appears in cell division which eventually moves the chromatids apart is called the?
spindle apparatus

What structure is most closely associated with the production of the mitotic spindle?
The centrosome is most closely associated with the production of the mitotic spindle. It is responsible for organizing the microtubules that make up the spindle fibers during cell division.
What is the array called when spindle fibers radiate from the centrosomes?
The array is called the mitotic spindle. It is made up of microtubules that radiate from the centrosomes and are crucial for the separation of chromosomes during cell division.
What act as focal points for the growth of the mitotic spindle?
Centrosomes are the main focal points for the growth of the mitotic spindle in eukaryotic cells. They contain pairs of centrioles that organize microtubules during cell division. The microtubules extend and form the spindle apparatus, which helps separate the chromosomes during mitosis.
What is the spindle in biology?
In biology, the spindle is a structure made up of microtubules that forms during cell division (mitosis and meiosis). It helps separate the chromosomes and ensure each daughter cell receives the correct number of chromosomes.
The assembly of microtubules is responsible for the movement of chromosomes during anaphase is called what?
The assembly of microtubules responsible for moving chromosomes during anaphase is called the mitotic spindle. It is composed of microtubules that attach to chromosomes and help separate them into two new daughter cells during cell division.
