During prophase, this is what the nucleus does:

  • The chromatin coils into double rod-shaped structures called chromosomes.
  • The chromatin becomes visible.

Okay, so now: Since the genetic material has been replicated in the prior interphase of the cell cycle, there are two identical copies of each chromosome in the cell, called homologous chromosomes. Identical chromosomes, called sister chromatids, are attached to each other at a DNA element present on every chromosome called the centromere.

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.


Is the nucleus of a cell contained within the nucleolus?

No, the nucleus is a membrane-bound organelle that houses the cell's genetic material, including the nucleolus. The nucleolus is a region within the nucleus where ribosomal RNA synthesis and ribosome assembly occur.


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.


Describe the changes that have occurred to the nucleolus and nuclear membrane from interphase to prophase?

During interphase, the nucleolus is visible and active in producing ribosomes, while the nuclear membrane is intact, surrounding the nucleus. As the cell enters prophase, the nucleolus begins to disappear as the ribosomal RNA is dispersed throughout the nucleus. The nuclear membrane also breaks down, allowing the chromosomes to condense and become visible.


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.

In Which phase the nucleolus begins to fade from view of the cell cycle?

The nucleolus begins to fade from view during prophase.


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.

What two structures disappear during prophase?

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

In what phase does the nucleus and nucleolus become visible?

I am pretty sure it's Prophase. But you should look it up just to make sure.No, that answer is wrong. It's Telophase. The nucleolus does the opposite and begins to disappear during Prophase.


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.


In mitosis when does the 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 broken down during prophase?

The nucleus.
