CENTRIOLES
Centrioles are barrel-shaped rings composed of microtubules that help move chromosomes around when a cell divides. Centrioles are involved in microtubule formation during cell division and the formation of cilia and flagela.

During mitosis chromosomes are moved and separated through the use of spindles composed of?
microtubules. These microtubules are formed from the centrosomes and attach to the chromosomes at their kinetochores. As the microtubules shorten and lengthen, they pull the chromosomes apart, ensuring that each daughter cell receives the correct number of chromosomes.
What phase do microtubules attach to kinetochores?
Microtubules attach to kinetochores during the prometaphase stage of cell division. This attachment is essential for the proper alignment and segregation of chromosomes during mitosis.
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.
Why does mitosis have to have microtubules in order to occur?
Microtubules are necessary for mitosis because they form the spindle fibers that help separate the duplicated chromosomes into two identical sets. These spindle fibers attach to the chromosomes and pull them apart during cell division. Without microtubules, proper chromosome segregation and successful cell division would not be possible.
At prometaphase of mitosis?
At prometaphase of mitosis, the nuclear envelope breaks down, allowing the condensed chromosomes to fully capture and attach to the mitotic spindle through their kinetochores. This stage is marked by the movement of chromosomes towards the center of the cell in preparation for proper alignment at the metaphase plate. Microtubules from opposite spindle poles attach to each sister chromatid of the chromosomes.
What guide chromosomes during mitosis?

Where do microtubules attach to chromosomes during mitosis?
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
What is the function of the centriole pair?
It organizes the microtubules in mitosis. The microtubules move the chromosomes around the cell during mitosis, most importantly lining the chromosomes up at the metaphase plate in metaphase so that they can split up into the two daughter cells.

What is the phase of mitosis dose the microtubules at eatheir and of a cell attach to the chromsomes and engagein a tug of war?
This phase of mitosis is called metaphase. During metaphase, the microtubules from opposite poles of the cell attach to the centromeres of the chromosomes. The microtubules then exert force to align the chromosomes at the center of the cell, forming the metaphase plate.
What is congression of chromosomes?
movement of chromosomes to spindle equator during mitosis is also known as congression of chromosomes.
What guides the chromosomes movement during mitosis?
The spindle fibers, composed of microtubules, help guide the movement of chromosomes during mitosis. The microtubules attach to the centromere region of the chromosomes and pull them towards opposite poles of the cell. This ensures that each daughter cell receives the correct number of chromosomes.
What is responsible for moving chromosomes during mitosis?
The mitotic spindle, which is made up of microtubules, is responsible for moving chromosomes during mitosis. The spindle fibers attach to the chromosomes at their kinetochores and help segregate them into two daughter cells.
The arrangement of microtubules that become visible during mitosis and that separate the chromosomes into equal groups is called the?
the answer is spindle (or spindle fibers)
