During prophase of mitosis, the chromosomes condense and become visible, and the mitotic spindle begins to form. The centrosomes, which are the microtubule-organizing centers, move toward opposite poles of the cell. This movement helps to establish the spindle apparatus that will later align and separate the chromosomes during metaphase and anaphase.

What cell parts migrate to the poles during pro phase?
During prophase of mitosis, several key cell parts migrate to the poles. The centrosomes, which organize the mitotic spindle, move to opposite poles of the cell. Additionally, spindle fibers, made of microtubules, extend from the centrosomes and begin to attach to the chromosomes. This organization is crucial for the proper separation of chromosomes in later stages of cell division.
What is the exchange of DNA between homologous chromosomes during pro phase of meiosis?
Crossing over or chromosomal crossover.
During which phase of the cell cycle are the chromosomes not individually visible?
During the interphase of the cell cycle, chromosomes are not individually visible. Instead, they are uncoiled and spread throughout the nucleus as chromatin. This phase is focused on growth, organelle replication, and preparing for cell division.
What happens after pro phase?
After prophase in cell division, the next stage is metaphase. During metaphase, the chromosomes align at the cell's equatorial plane, known as the metaphase plate. This alignment is crucial for ensuring that each daughter cell receives an identical set of chromosomes during the subsequent stages of division. Following metaphase, the cell proceeds to anaphase, where the sister chromatids are pulled apart to opposite poles of the cell.
Why chromatin thicken and shorten during prophase?
Through successive rounds of mitosis, replication of DNA in the S-phase of interphase results in shorter and shorter chromosomes. The structures called telomeres are attached to the ends of the chromosomes to prevent the chromosomes from becoming too short.
What can no occur during pro phase 2 that happens in pro phase 1?
Crossing-over

Are chromosomes visible during pro-phase?
yes they are now visible during prophase
Which structure becomes visible during pro-phase?
duplicated cell wall.
Why does nucleolus disappear during pro-phase of mitosis and what is the mechanism of dissapearence?
The nucleolus disappears during prophase of mitosis because it is the stage where the nuclear envelope breaks down, causing the nucleolus to disperse. This disappearance is due to the disassembly of the nucleolar components and the redistribution of its content throughout the cell.
The nucleus and nucleus disappear during?
Nucleous is dissapeared in pro phase.It re appear in telo phase.

AWS Pro Moves Soccer happened in 1993.
What is the exchange of DNA between homologous chromosomes during pro phase of meiosis?
Crossing over or chromosomal crossover.
What happens after pro-phase?
Metaphase
What results from th eprocess of crossing-over during prophase 1?
During the crossing-over of pro phase 1, chromosomes of a homologous pair break and exchange genes.
what is the phases of mitosis?
The 4 phases are- 1. Pro phase 2. meta phase 3. ana phase 4. Telo phase
