What organelle coordinates the movement of chromosomes during mitosis in animal cells?
The organelle that coordinates the movement of chromosomes during mitosis in animal cells is the centrosome. The centrosome serves as the main microtubule organizing center, producing spindle fibers that attach to chromosomes at their kinetochores. These spindle fibers help align and separate the chromosomes, ensuring their proper distribution into the daughter cells.
What is the organelle that forms spindle fibers that split and pull chromosomes to opposite ends of the cell?
The organelle responsible for forming spindle fibers during cell division is the centrosome. The centrosome is composed of two centrioles and plays a critical role in organizing and anchoring the spindle fibers that help separate the chromosomes during mitosis.
What is the area near the nucleus that is made of two centrioles?
The area near the nucleus that is made of two centrioles is the centrosome. Centrioles play a key role in cell division by organizing the spindle fibers that separate the chromosomes during mitosis.
In which steps of mistosis do the fibers appear?
The fibers, known as spindle fibers, appear during prophase of mitosis. They begin to form as the centrosomes move to opposite poles of the cell, and the microtubules extend from the centrosomes. These fibers attach to the chromosomes at their kinetochores during prometaphase, facilitating their alignment and separation in subsequent stages.
What are chromosomes separated by during mitosis?
the spindle fibers

During mitosis in animal cells spindle fibers extend from the centrioles which are located at opposite sides of the cells true or false?
true
Cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called?
The cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called spindle fibers or mitotic spindles. They help in the separation of chromosomes during mitosis or meiosis by attaching to the centromeres.
During this stage of mitosis, when do the chromosomes become attached to the spindle fibers?
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
Which structure organizes the mitotic spindle during cell division?
The centrosome, made up of two centrioles, plays a crucial role in organizing the mitotic spindle during cell division. The centrosomes move to opposite ends of the cell and serve as the poles for the spindle fibers to attach and pull the chromosomes apart during mitosis.
What does the controsome do in the animal cell?
The centrosome is a structure in animal cells that helps organize the microtubules during cell division. It plays a key role in the formation of the spindle fibers that are involved in separating the chromosomes during mitosis.
Produce spindle fibers?
Centrioles. They are visible during metaphase, the second stage of mitosis. Added: Centrosomes. Centrioles are present in animal cells but are, seemingly, not needed to mount a spindle apparatus. Plant cells get along very well without centrioles.
What are chromosomes separated by during mitosis?
the spindle fibers
What kind of fibers do animal and plants have during mitosis?
spindle
When during mitosis do chromosomes attach to spindle fibers?
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region of the chromosomes.
