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?
The three major components of the nucleus are the nuclear envelope, nucleolus, and chromatin. The nuclear envelope is a double membrane that surrounds the nucleus, the nucleolus is involved in ribosome production, and chromatin is a complex of DNA and proteins that make up chromosomes.
Besides the nucleus what else is broken down during prophase?
Nuclear membrane and nucleolus
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.
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 cell parts begin to reappear during telophase?
The chromosomes go to opposite poles, the nuclear envelope reappears and cleavage furrow deepens
What two structures disappear during prophase?
During prophase, the nuclear membrane and the nucleolus dissolve and disappear.

When do nuclear membrane and nucleolus disappear?
The nuclear membrane and nucleolus both disappear during prophase of mitosis and meiosis.The nucleolus is a region of the interphase nucleus containing many of the genes that code for ribosomal RNAs (rRNAs). The genes are on a number of different chromosomes, which have to folded in such a way that these genes end up in the same region of the nucleus. During prophase the chromosomes separate from one another, and so the nucleolus disappears.The nuclear membrane has to be taken out of the way before metaphase, so that the chromosomes can move out of the confines of the nucleus. Enzymes break down the membrane into small fragments, which travel through the endoplasmic reticulum to the poles. They will be used to construct new nuclear membranes around the daughter nuclei during telophase.##One thing should be remain that nuclear membrane never disappeared just disorganized when RNA come out from nucleolus. Again its reorganized when RNA form in nucleolus.prophase

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
Besides the nucleus what else is broken down during prophase?
Nuclear membrane and nucleolus
Where is the nucleolus found in a animal cell?
In the nuclear membrane
What does the nuclear membrane disappear?
Anaphase
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.
