What act as focal points for the growth of the mitotic spindle?
Centrosomes are the main focal points for the growth of the mitotic spindle in eukaryotic cells. They contain pairs of centrioles that organize microtubules during cell division. The microtubules extend and form the spindle apparatus, which helps separate the chromosomes during mitosis.
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.
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.
What processes separate eukaryotic chromosomes?
Mitosis and Meiosis
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 responsible for moving chromsomes during mitosis?
microtubules or cytoskeleton (as in centrioles)
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 are spindle fibers composed of?
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
The actual process of cell division in eukaryotic cells is called?
Nuclear division in eukaryotic cells is called mitosis.
In the telophase stage of mitosis microtubules gather along the cell's equator The purpose of these microtubules is to?
D. assemble materials that will form the new cell wall.
What processes separate eukaryotic chromosomes?
Mitosis and Meiosis
Do eukaryotic cells undergo mitosis?
Yes, eukaryotic cells undergo mitosis during the cell cycle in order to replicate and divide. Mitosis is the process by which a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell.

What organelle has two short microtubules at right angles and have an active role in mitosis?
centriole
