During cell division, the nuclear membrane breaks down to allow the chromosomes to separate and be distributed into the daughter cells. The nucleolus, which is responsible for ribosome synthesis, also disassembles during this process. Once cell division is complete, the nuclear membrane reforms around each set of chromosomes, and the nucleolus reappears in the newly formed nuclei.
What else can I help you with?
Is the nucleolus part of the nuclear membrane?
No - the membrane is what separates the nucleus from the cytoplasm.
What happens to the nuclear membrane to allow chromosomes to drawn apart?
It begins to dissolve. Some sort of signal is sent to the Nucleolus to start dissolving it's membrane.
What are the components of the nucleus?
Nucleus has nucleolus, nuclear membrane and the genome. Nuclear membrane containing pores that transport molecule across the membrane. Nucleolus makes rRNA and ribosomes. Genome has all chromosomal DNA that express a gene or a character.
When does the nucleolus begin to fade away?
The nucleolus begins to fade away during cell division (mitosis) when the nuclear membrane breaks down. As the cell prepares to divide, the nucleolus disassembles, and its components are dispersed throughout the cell.
In the first stage of cell reproduction the what disappears?
the sperm
In what stage does the nucleolus and nuclear membrane disappear and spindle fibers and centrioles appear?
The Microtubules of the bipolar spindle assemble and attach sister chromatids to opposite spindle pole, This happens at the Transition into Metaphase.
What are the three major components of the nucleus?
Nucleus has nucleolus, nuclear membrane and the genome. Nuclear membrane containing pores that transport molecule across the membrane. Nucleolus makes rRNA and ribosomes. Genome has all chromosomal DNA that express a gene or a character.
What is the nuclear membranes job?
the nuclear membrane's job is to protect the nucleolus, and to control what goes in, and out of the membrane.
Is the nucleolus part of the nuclear membrane?
No - the membrane is what separates the nucleus from the cytoplasm.
What does nuclear membrane and nucleolus?
It seperate cytoplasm and nucleus. Nucleolus build up ribosomes
Where is the nucleolus found in a animal cell?
In the nuclear membrane
What happens to the nuclear membrane to allow chromosomes to drawn apart?
It begins to dissolve. Some sort of signal is sent to the Nucleolus to start dissolving it's membrane.
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 are the components of the nucleus?
Nucleus has nucleolus, nuclear membrane and the genome. Nuclear membrane containing pores that transport molecule across the membrane. Nucleolus makes rRNA and ribosomes. Genome has all chromosomal DNA that express a gene or a character.
What two structures disappear during prophase?
During prophase, the nuclear membrane and the nucleolus dissolve and disappear.
When does the nucleolus begin to fade away?
The nucleolus begins to fade away during cell division (mitosis) when the nuclear membrane breaks down. As the cell prepares to divide, the nucleolus disassembles, and its components are dispersed throughout the cell.
In the first stage of cell reproduction the what disappears?
the sperm
