What else can I help you with?
Which cellular structure disappears from the screen just as the cell leaves interphase and progresses into prophase?
nucleolus
Does the nucleolus disappear in mitosis?
Each diploid cell in the human body has one nucleolus which disappears at the onset of mitosis and is replaced by ten tiny nucleoli, five of which eventually come together to form the nucleoli of each new cell.
What structure within the nucleus becomes indistinct and finally disappears as the cell progresses through prophase?
nucleolus
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.
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.
What two structures disappear during prophase?
During prophase, the nuclear membrane and the nucleolus dissolve and disappear.
What is the nucleolus's function?
Nucleolus is where ribosomes are made. Ribosomes are made up of RNA and several proteins, and they are a necessary part in the synthesis of proteins. An interesting fact about the nucleolus is that they disappear during cell reproduction. This is probably because the need for ribosomes disappears during cell reproduction.
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.
What disappears in the prophase of mitosis?
"...the nuclear envelope and the nucleolus break up, dispersing, and are no longer visible..." (Hole's essentials of human anatomy & physiology, 67).
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.
In the first stage of cell reproduction the what disappears?
the sperm
What is the role of the nucleolus in cell division?
to divide the cell in half, resulting in the process of meiosis i dont know what a nucleolus does really but its in the middle f the nucleus so it must be important It is not involved in cell division. it disappears during beginning of cell division and reappears during telophase of cell division. Nucleolus helps in the synthesis of Ribosomes (organelles that help in protein synthesis).
