The Microtubules of the bipolar spindle assemble and attach sister chromatids to opposite spindle pole, This happens at the Transition into Metaphase.

What two structures disappear during prophase?

During prophase, the nuclear membrane and the nucleolus dissolve and disappear.


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 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 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


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 does the nuclear membrane disappear?
