Nuclear envelope
What else can I help you with?
What is broken down during prophase?
The nucleus.
Besides the nucleus what else is broken down during prophase?
During prophase, the nuclear membrane breaks down, allowing the condensed chromosomes to be released into the cytoplasm. Additionally, the centrioles move to opposite poles of the cell and the spindle fibers begin to form.
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 within the nucleus disappears during prophase?
The nuclear envelope.
In what phase does chromosomes condense and become visible?
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
During which stage of mitosis does the nucleus break down?
The breakdown of the nucleus occurs in the prophase stage of mitosis. This is when the nuclear envelope disintegrates, allowing the chromosomes to be released into the cytoplasm for subsequent division.
What phase of mitosis does the nuclear envelope and the nucleus disappear and a spindle forms?
The phase of mitosis where the nuclear envelope and nucleus disappear is called prophase. During prophase, the chromatin condenses into discrete chromosomes, and the spindle apparatus begins to form, facilitating the movement of chromosomes during cell division.
What structures are becoming visable as distinct bodies within the nucleus during prophase?
Chromosomes
What part of the cell takes up opposite sides of the nucleus during prophase?
CENTRIOLES
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.
During this phase of mitosis two centrioles appear to one side of the nucleus.?
prophase
