This is related to mitosis. Once the chromosomes are fully condensed, the nuclear envelop is disolved in order to let the mitotic spindle is put in it's place to migrate the chromatids to the poles. Once the chromatids have already migrated, the cytokinesis process take place, dividing the cell into two daughter cells that eventually rebuild their nuclear envelop.
What else can I help you with?
When does the nuclear membrane and nucleolus reappear?
The nuclear membrane reforms during late telophase of mitosis or meiosis, while the nucleolus reappears during interphase.
In what stage does the nuclear membrane disintegrate?
Mitosis Prophase. Yep one homework question answered!
The nucleolus disappears and the nuclear envelope breaks down?
This process occurs during mitosis in eukaryotic cells. As the cell prepares to divide, the nucleolus, which is responsible for producing ribosomes, disappears. Additionally, the nuclear envelope breaks down to allow the chromosomes to separate into two daughter cells.
What happens during late prophase?
The late prophase is one of the stages in mitosis and during this stage there is a break up of the nuclear envelope and the microtubules that the spindle fibers are made up of called the polar fibers reach from the pole to the equator of each cell. Specialized regions that are in the centromeres of chromosomes called Kinetochores attach to kinetochore fibers which are a type of microtubules. The spindle polar fibers connect the polar fibers to the kinetochores through their interaction with the kinetochore fibers and the chromosomes start to migrate towards the center of the cell.
What separates the nucleus from the rest of the cell?
during mitosis the spindle fibre seperates the sister chromatids , two on both sides of the cell. while the spindle fiber moves towards the pole this dividing of separate chromosome happens. also during late mitotic stage the nuclear material divides into two and eventually the cell membrane constricts dividing the cytoplasm to form two individual daughter cells.During mitosis, the cell itself separates. The nuclear envelope is dissolved, the already replicated chromosomes segregate. The two new cells. They each have a normal number/ complement of chromosomes.

In prophase do the nuclear membrane dissapears?

What happens to the nuclear membrane during telophase II?
During telophase II of meiosis, the nuclear membrane reforms around the separated daughter nuclei, enclosing them in their own distinct compartments. This process completes the formation of four genetically unique haploid daughter cells, each with its own nucleus surrounded by a nuclear membrane.

What phase is the early and a late stage of the the same phase of mitosis?
The early and late stages of the same phase of mitosis are called prophase. Prophase is the first stage of mitosis where the chromatin condenses into chromosomes and the nuclear membrane breaks down. The late stage of prophase is characterized by the alignment of chromosomes along the equator of the cell.
A synaptonemal complex disappears during?
The synaptonemal complex disappears during the diplotene stage of meiosis. This dissolution marks the end of the physical connection between homologous chromosomes, allowing them to separate and continue with the process of meiosis.
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.
Do giraffe have gallbladder?
In giraffes, a gallbladder is usually present in the fetus, but disappears in late gestation. The presence of a gallbladder in a giraffe calf is considered an anomaly.
