In animal cells, organelles called Centrioles are responsible for the formation of spindle fibres during cell division. In diploid cells, there is a pair of centrioles present. In the Anaphase stage, these move to opposite poles of the cell and after the spindle fibres attach to the chromosomes, pull them to the respective side. Each centriole is made of two identical cartwheel-like components, positioned at right angles to each other.
What else can I help you with?
What organelle is a key part in mitotic spindle?
If you look at certain pictures taken of the spindles/an artists representation of them, you will find that the nucleus, the mitochondria, and the Golgi Apparatus all play a significant role in mitotic spindles.
The mitotic spindle formation depends upon?
The formation of the mitotic spindle depends upon the proper assembly and organization of microtubules, which are dynamic protein fibers that make up the spindle apparatus. Microtubules are regulated by microtubule-associated proteins that help facilitate their polymerization and depolymerization processes. Additionally, motor proteins are essential for moving the chromosomes to their correct positions during mitosis.
What is the site of spindle formation?
Spindle formation occurs in the centrosome, a cellular organelle that serves as the main microtubule-organizing center in animal cells. The centrosome helps to assemble and organize the microtubules that make up the spindle apparatus during cell division.
What organelle is sructure involved in mitosis in animal cell only?
The organelle involved in mitosis in animal cells is the centrosome. It contains a pair of centrioles that play a crucial role in organizing the spindle fibers necessary for chromosome separation during cell division. Unlike plant cells, which do not have centrioles, animal cells rely on centrosomes to ensure proper mitotic spindle formation. This structure is essential for the accurate distribution of chromosomes to the daughter cells.
What structure forms in prophase along which the chromosomes called?
The answer is Spindle Fibers.
What directs the formation of the mitotic spindle?
The mitotic spindle is directed in its formation by microtubules, which are dynamic protein filaments that organize into a bipolar structure during cell division to help separate the chromosomes. Microtubules are controlled by motor proteins and regulatory proteins that ensure proper spindle formation and function. Various signaling pathways and cell cycle checkpoints also play a role in orchestrating the assembly and positioning of the mitotic spindle within the cell.
What organelle is a key part in mitotic spindle?
If you look at certain pictures taken of the spindles/an artists representation of them, you will find that the nucleus, the mitochondria, and the Golgi Apparatus all play a significant role in mitotic spindles.
One event occurring during prophase is?
The begining of the formation of the mitotic spindle-During prophase, the mitotic spindle begins to form.
Why does the vincristine drug damages the mitotic spindle?
Vincristine disrupts the formation and function of the mitotic spindle by binding to tubulin, a protein that helps in spindle formation. This interferes with the normal process of cell division, leading to mitotic arrest and ultimately cell death.
This organelle found in animal cells functions in cell division and aids in spindle formation?
The organelle you are referring to is the centrosome. It contains a pair of centrioles and helps organize microtubules during cell division to form the mitotic spindle, which is essential for segregating chromosomes.
What cell organelle controls cell reproduction?
Centrosome. It is a pair of centrioles plus pericentriolar material. The pericentriolar material contains tubulins, which are used for growth of the mitotic spindle and microtubule formation. The mitotic spindle are used in reproduction. Reference: Principles of Anatomy and Physiology. 12th Ed. Author: Tortora, Derrickson.
