Does a prokaryotic cell have a plasma membrane?
The prokaryotic cells have a plasma membrane. They do not have a membrane around their nuclear material. Pro- means before. Karyo- means "nut" or nucleus.
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 the biggest difference between prokaryotes and eukaryotes?
The biggest difference between prokaryotes and eukaryotes is the presence of a distinct nucleus in eukaryotes, which houses the genetic material. Prokaryotes lack a nucleus and their genetic material is located in the cytoplasm. Eukaryotes also have membrane-bound organelles, whereas prokaryotes do not.
What happens to the nuclear envelope towards the end of cell division?
During prophase the nuclear membrane disintegrates. The metaphase through anaphase the molecules are not formed as membranes. During telophase it reintegrates and in interphase it is present as normal.
How many nuclear membranes must form before telophase?
Two nuclear membranes must form before telophase, as the nuclear envelope reforms around the individual sets of chromatids within each daughter cell.
What happens to chromosomes before the nuclear membrane breaks down in mitosis?
Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
What happens to the nuclear material of the parent cell before it divides?

When does the nuclear membrane dissolve in mitosis?
Hello :) Nuclear membrane breaks right before metaphase 1 which is Prophase 1 thank U
What is nuclear membrane analogy for mall?
The nuclear membrane could be likened to security at a mall entrance, controlling what enters and exits the nucleus like security screening at a mall. The nuclear pores act as checkpoints, allowing specific molecules to pass through, similar to how security checks certain items before allowing them into the mall. This analogy helps us visualize the selective permeability of the nuclear membrane.
What is the nuclear membrane and what does it do?
The nuclear membrane is a double membrane surrounding the chromosomes of a eukaryotic cell.Together with associated structures, it is called the nuclear envelope. Perforations in the double membrane are termed pores; each is surrounded by a group of proteins collectively called the nuclear pore complex.The nuclear membrane defines the limit of the organelle called the nucleus. The membrane is broken into fragments during the first phase (prophase) of nuclear division. The fragments travel through the endoplasmic reticulum to the poles of the dividing cell, and are used to form the nuclear membranes of the daughter-cells.The pores permit large molecules to enter and leave the nucleus. For example, after transcription messenger RNA passes through a pore on its way to the cytoplasm for translation. And proteins synthesized in the cytoplasm enter the nucleus via pores before being incorporated in ribosome subunits being assembled in the nucleolus. These subunits subsequently leave the nucleus through the pores.

What happens to nuclear energy before it is used?
Nuclear energy is released as heat in the fuel of a nuclear reactor, but only when the reactor has been brought to criticality and the chain reaction started. At that point the heat must be used, it can't be stored and used later. Before criticality is established, the reactor is shutdown and producing no nuclear heat from fission, so you could regard it as having potential nuclear energy in that state

What happens during telopase?
During telophase, the chromosomes reach the opposite poles of the cell, and the nuclear membrane reforms around each set of chromosomes. The chromosomes begin to decondense back into chromatin, and the spindle fibers disassemble. Telophase is the final stage of mitosis before cytokinesis occurs, resulting in two identical daughter cells.
