What is responsible for moving chromosomes during mitosis?

What stage when spindle fibers attach to chromosomes?
The stage when spindle fibers attach to chromosomes is during metaphase of mitosis or meiosis. Spindle fibers, which are made of microtubules, attach to the centromere region of chromosomes to help separate them correctly during cell division.
How are microtubules and spindle fibers involved in the process of cell division?
Microtubules and spindle fibers play crucial roles in cell division. Microtubules help separate chromosomes during mitosis by forming the mitotic spindle, a structure that helps move and align chromosomes. Spindle fibers, which are made of microtubules, attach to chromosomes and help pull them apart during cell division. Overall, microtubules and spindle fibers ensure that each daughter cell receives the correct number of chromosomes.
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.
What attaches to chromosomes during mitosis?
During mitosis, the chromosomes are pulled away by spindle fibers that come from each pair of centrioles at the opposite ends of the cell. The reason this happens is so that each new daughter cell gets the same chromosomes as the parent cell had.
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.
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.
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 stage when spindle fibers attach to chromosomes?
The stage when spindle fibers attach to chromosomes is during metaphase of mitosis or meiosis. Spindle fibers, which are made of microtubules, attach to the centromere region of chromosomes to help separate them correctly during cell division.
At prometaphase of mitosis?
During prometaphase, the nuclear envelope fragments and the spindle microtubules are able to reach the chromosomes. Each of the two chromatids of each chromosome, at this point, has a kinetochore. The microtubules attach to the kinetochores, forming "kinetochore microtubules" which basically jerk the chromosomes back and forth.
During mitosis microtubles attach to chromosomes at the?
kinetochores, which are protein structures found at the centromere of each chromosome. The microtubules attach to the kinetochores and help to accurately separate the duplicated chromosomes into two daughter cells during cell division.
Why does mitosis have to have microtubules in order to occur?
Mitosis require microtubules because they bind to the chromosomes and pull them to each pole of the cell. The cell can then divide with the respective chromosomes on separate halves of the cell.
What structures pull the chromosomes apart?
The spindle fibers, which are composed of microtubules, pull the chromosomes apart during cell division. These fibers attach to the centromeres of the chromosomes and help guide them to opposite poles of the cell during mitosis or meiosis.
What is cellular component helps for the chromosomes apart in mitosis and meiosis?
The cellular component that helps pull chromosomes apart during mitosis and meiosis is the spindle apparatus, which is made up of microtubules. These microtubules extend from the centrosomes (or spindle poles) and attach to the kinetochores of the chromosomes. As the spindle fibers shorten, they exert tension that separates sister chromatids during mitosis and homologous chromosomes during meiosis. This process ensures accurate distribution of genetic material to the daughter cells.
How do the daughter chromosomes reach the opposite ends of the cell during mitosis?
During mitosis, the daughter chromosomes reach opposite ends of the cell through the action of the spindle apparatus, which consists of microtubules. These microtubules attach to the kinetochores of the chromosomes and pull them apart during anaphase. The motor proteins, such as dynein and kinesin, facilitate this movement along the microtubules, ensuring that the chromosomes are accurately segregated into the two daughter cells. This coordinated process ensures proper distribution of genetic material during cell division.
What guide or pull chromosomes during mitosis?
The mitotic spindle, comprised of microtubules, guides and pulls chromosomes during mitosis. The spindle fibers attach to the centromeres of sister chromatids and help separate them to opposite poles of the cell during cell division.
