Which organelle sends out microtubles that connect to DNA during metaphase?
The organelle responsible for sending out microtubules that connect to DNA during metaphase is the centrosome. The centrosome organizes the microtubules into a structure known as the mitotic spindle, which attaches to the chromosomes at their kinetochores. This connection is crucial for the proper alignment and separation of chromosomes during cell division.
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 the Phase of mitosis in which microtubules connect thecentromere of each chromosome to the poles of spindle?
The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation during anaphase.
What structure forms in metaphase?
In metaphase, the chromosomes line up along the metaphase plate in the center of the cell. Microtubules from opposite poles of the cell attach to the centromere of each chromosome to help align them properly for separation during anaphase.
What region of the chromosome serves as the attachment site for microtubules during Cell division?
The kinetochore is the region of the chromosome that serves as the attachment site for microtubules during cell division. It is a protein structure that forms on the centromere of a chromatid. Kinetochore microtubules connect the chromatids to the mitotic spindle to aid in the separation of chromosomes during mitosis.

When and how is the spindle formed?
The spindle is formed during cell division, specifically during the metaphase stage of mitosis or meiosis. It is made up of microtubules and associated proteins, organized by the centrosomes at opposite poles of the cell. These microtubules help to separate chromosomes during cell division.

The phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of the pindle?
The name for the network of microtubules along which the chromosomes move during cell division is called the spindle fibers. These spindle fibers attach to the chromosomes and pull them in half.
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.
Why is colchicine used for preparing a metaphase spread?
Colchicine is a drug that prevents tubulin polymerisation into cytoskeleton structures called microtubules. Microtubules are essential for many functions of the cell, but importantly are needed for cell division. Specifically, they help align homologous chromosomes on the metaphase plate during metaphase and then separate the chromosome pairs during anaphase. So by inhibiting the production of microtubules, the chromosomes never align on the metaphase plate - they will be fully condensed but spread throughout the cell, a situation called a metaphase spread
What pulls chromosomes during during mitosis?
During metaphase, the spindles, or microtubules, all start to move to opposite ends. There, they grab the chromatids and pull them back to their opposite sides.
Where are chromosomes located during metaphase?
Chromosomes are located at the center of the cell during metaphase, aligned along the metaphase plate. This alignment ensures that each chromosome is properly attached to the spindle fibers before they are separated during anaphase.
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.
What structure forms in metaphase?
In metaphase, the chromosomes line up along the metaphase plate in the center of the cell. Microtubules from opposite poles of the cell attach to the centromere of each chromosome to help align them properly for separation during anaphase.
During the metaphase stage of mitosis?
During the metaphase stage of mitosis, the chromosomes align at the equatorial plate, forming a metaphase plate. The microtubules from opposite poles attach to the kinetochores on the sister chromatids, allowing for equal segregation of genetic material during anaphase. This alignment ensures that each daughter cell will receive an identical set of chromosomes.
During metaphase the centrometers attach to what structures?
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
