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.
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 phase is when each chromosome is connected to a spindle fiber?
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.
Why is crossing-over during meiosis important?
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
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.
When was AWS Pro Moves Soccer created?
AWS Pro Moves Soccer was created in 1993.
When did AWS Pro Moves Soccer happen?
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.
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 is the phases of mitosis?
The 4 phases are- 1. Pro phase 2. meta phase 3. ana phase 4. Telo phase
