When the nucleus disappears during prophase it fragments into which fuse to reform the nucleus during telophase?
When the nucleus disappears during prophase, it fragments into vesicles containing membrane and nuclear pore proteins. These vesicles then fuse together to reform the nucleus during telophase.
What structure are becoming visible as distinct bodies within the nucleus during prophase?
chromosomes
What is a paired structure that appear next to the nucleus during prophase to separate chromosomes?
The centrosomes.
What is the Phase where nucleus disappears?
The phase where the nucleus disappears is known as prophase during mitosis. In this stage, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the spindle apparatus to interact with the chromosomes. This disappearance of the nucleus is crucial for the subsequent alignment and separation of chromosomes during cell division.
In what phase does the nucleus disappear?
The nucleus disappears during prophase of mitosis. In this phase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the microtubules to access the chromosomes. This dissolution of the nucleus is crucial for the subsequent steps of cell division.
Does the nucleus disappear during mitosis and meiosis?
No, the nucleus does not disappear during mitosis or meiosis. It undergoes changes in structure and organization, such as condensation of the chromatin into visible chromosomes, but the nucleus remains present throughout these processes to ensure proper segregation of genetic material.
What is broken down during prophase?
The nucleus.
In which phase does the nuclear envelope disappear?
The nuclear envelope disappears during the prophase stage of mitosis. This allows the chromosomes to be free within the cell and facilitates their separation and movement during cell division.
Chromatin threads change to dense rods during the process of?
Chromatin changes to thick rods called chromosomes during anaphase. During anaphase the centromeres divide and are pulled apart by the spindle fibers. They then move to opposite ends of the poles.
What stage of mitosis does the nucleolus disappears?
The nucleolus disappears during the prophase stage of mitosis when the nuclear envelope breaks down, chromosomes condense, and the spindle apparatus begins to form. This is in preparation for the separation of genetic material into two daughter cells.
The nucleus and nucleolus disappear during what?
The nucleus and nucleolus disappear during cell division, specifically during the prophase stage of mitosis. This is when the nuclear envelope breaks down, allowing the chromosomes to condense and become visible. The nucleolus also disappears as the cell prepares to divide into two daughter cells.
What is the phase in mitosis where the nuclear membrane disappears?
"scientist have not discovered WHY it happens"It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASEHope this helped!!!
