Crossing over or chromosomal crossover.
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.
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.
The phase where each chromosome is connected to a spindle fiber is called metaphase. During metaphase, the chromosomes align at the metaphase plate at the center of the cell, and each chromosome is attached to spindle fibers emanating from opposite poles of the cell.
crossing over during meiosis is important in that it allows the occurrence of various genes, this is it promotes the increase of different genes. lets remember that meiosis occurs in sexually producing animals and that the first phase of meiosis is the reduction of the haploid number to the diploid number. this reduces the occurrences of increasing numbers in chromosomes. crossing over takes place during pro-phase
Crossing-over
yes they are now visible during prophase
duplicated cell wall.
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.
Nucleous is dissapeared in pro phase.It re appear in telo phase.

Crossing over or chromosomal crossover.
Metaphase
During the crossing-over of pro phase 1, chromosomes of a homologous pair break and exchange genes.
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.
The 4 phases are- 1. Pro phase 2. meta phase 3. ana phase 4. Telo phase
