During which phase of the cell cycle are the chromosomes not individually visible?
Interphase, because during pro phase they become visible so that means in interphase they were not visible.
What is the exchange of DNA between homologous chromosomes during pro phase of meiosis?
Crossing over or chromosomal crossover.
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.
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 makes the chromosomes become visible during prophase?
When pro phase begins, the DNA molecules are progressively shortened and condensed by coiling, to form visible chromosomes.
What can no occur during pro phase 2 that happens in pro phase 1?
Crossing-over
Why does nucleolus disappear during pro-phase of mitosis and what is the mechanism of dissapearence?
Nucleus and nucleolus disappear during pro-phase stage of mitosis,to be specific it disappears in late pro-phase stage and reappers during telophase stage of mitosis.
Are chromosomes visible during pro-phase?
yes they are now visible during prophase
Which structure becomes visible during pro-phase?
duplicated cell wall.
During which phase of the cell cycle are the chromosomes not individually visible?
Interphase, because during pro phase they become visible so that means in interphase they were not visible.
The nucleus and nucleus disappear during?
Nucleous is dissapeared in pro phase.It re appear in telo phase.
What is the exchange of DNA between homologous chromosomes during pro phase of meiosis?
Crossing over or chromosomal crossover.
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 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.
Which phase do chromosomes first become visible?
Interphase as they become decondenced
