The spindle fibers are the structures that form during the prophase which help in the movement of the chromosomes.. The spindle fiber grows from the microtubules which are extended from the centrioles at the opposite poles of the cell

Early microscopists were the first to observe these structures, and they also noted the appearance of a specialized network of microtubules during mitosis. These tubules, collectively known as the spindle, extend from structures called centrosomes — with one centrosome located at each of the opposite ends, or poles, of a cell
The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell

To test this hypothesis, we monitored chromosome movement during mitosis after perturbation of nuclear mitotic apparatus protein (NuMA) and the human homologue of the KIN C motor family (HSET), two noncentrosomal proteins involved in spindle pole organization in animal cells. Perturbation of NuMA alone disrupts spindle pole organization and delays anaphase onset, but does not alter the velocity of oscillatory chromosome movement in prometaphase
In contrast, simultaneous perturbation of both HSET and NuMA severely suppresses directed chromosome movement in prometaphase. Chromosomes coalesce near the center of these cells on bi-oriented spindles that lack organized poles

During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell division (cytokinesis)
Although many of the details of mitosis vary among different organisms, the fundamental processes that ensure the faithful segregation of sister chromatids are conserved in all eukaryotes. These basic events of mitosis include chromosome condensation, formation of the mitotic spindle, and attachment of chromosomes to the spindle microtubules

The cell cycle, mitosis and meiosis for higher education [8]
The cell cycle, mitosis and meiosis for higher education. Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides.
Each chromosome now consists of two sister chromatids.. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.
– The period between mitotic divisions – that is, G1, S and G2 – is known as interphase.. Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell
Phases of mitosis [9]
How a cell divides to make two genetically identical cells. What do your intestines, the yeast in bread dough, and a developing frog all have in common? Among other things, they all have cells that carry out mitosis, dividing to produce more cells that are genetically identical to themselves.
Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell’s nucleus is split into two equal sets of chromosomes.
During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones. For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population.

This relies on a mechanism to move chromosomes in defined directions within the parental cell. While sister chromatids are segregated from one another in mitosis and meiosis II, specific adaptations enable the segregation of homologous chromosomes during meiosis I to reduce ploidy for gamete production
Here we review the mechanisms of eukaryotic chromosome segregation, with a particular emphasis on the modifications that ensure the segregation of homologous chromosomes during meiosis I.. The accurate segregation of the genetic material in eukaryotes is guided by three basic principles: (1) Force needs to be generated to power the movement of the DNA

What structure is involved in moving chromosomes during mitosis? [14]
STRUCTURE INVOLVED IN MOVING CHROMOSOMES DURING MITOSIS. Duplicated centrioles are responsible for moving chromosomes during mitosis.
It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.. Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.
Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.. These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.

Chapter 6: Introduction to Reproduction at the Cellular Level. – Discuss the behavior of chromosomes during mitosis and how the cytoplasmic content divides during cytokinesis
The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produce two genetically identical cells
During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated and the cell divides.
Wikipedia [16]
Prophase (from Ancient Greek προ- (pro-) ‘before’, and φάσις (phásis) ‘appearance’) is the first stage of cell division in both mitosis and meiosis. Beginning after interphase, DNA has already been replicated when the cell enters prophase
Microscopy can be used to visualize condensed chromosomes as they move through meiosis and mitosis.[4]. Various DNA stains are used to treat cells such that condensing chromosomes can be visualized as the move through prophase.[4]
Fluorescent stains such as DAPI can be used in both live plant and animal cells. These stains do not band chromosomes, but instead allow for DNA probing of specific regions and genes
