The nuclear membrane or nuclear envelope is a double-bilayer fluid-filled selectively-permeable containment that surrounds the rest of a cell's nucleus. Within the envelope is nucleoplasm in which floats the chromatin and nucleolus; these hold the cell's genetic information and instructions in the f…orm of DNA and RNA.. When a cell is ready to divide by mitosis, the membrane decomposes to permit the nucleus to divide into two nuclei; then new membranes form to enclose the two new nuclei and cell division continues until two new complete cells are formed.. It keeps the DNA all in one location. It only allows certain molecules and proteins within and without the cell. The membrane has pores that decide whether or not stuff can exit or enter the nucleus. It controls the movement of substances such as mRNA and nucleotidesin and out of the nucleus. ( Full Answer )
A nuclear membrane is like the cell membrane except it protects the nucleus.. Nuclear membran is the double-layered membrane surrounding the nucleus in eukaryotic cells.. a specialized structure occurring in many cells and separated from the rest of the cell by a double layer, called the nuclear m…embrane. This membrane seems to be continuous with the endoplasmic reticulum of the cell and has pores. . It has holes that support materials with moving in and out of it.It works with the nucleus.

The interphase stages G1, S, & G2, begins the process in whichthe cell grows & matures. Followed by the S phase where the DNAis copied.
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. ( Full Answer )

The cell obtains nutrients, and it is considered as the living phase of the cell.
The cell is prepared for division by doubling the DNA and centromeres and adding spindle fibers
The nuclear membrane degrades in the part of mitosis called the"prometaphase". It is important because in the process ofcytokinesis (nucleus division) the new nucleus has to burst out ofthe parent nucleus. The disintegration of the nuclear membranemakes sure that the new nucleus will come out smooth…ly and easily.If the nuclear membrane didn't disintegrate, the new nucleus wouldburst from the parent nucleus and therefore will damage the cell.

Chromosomes during interphase only have one chromatin Found this answer while doing a crossword for my bio 101 class, it fits in the space - if that helps your confidence in my answer
During prophase the nuclear membrane disintegrates. The metaphasethrough anaphase the molecules are not formed as membranes. Duringtelophase it reintegrates and in interphase it is present asnormal.
Resulting from interphase, is a genetic material in the nucleus called chromatin. The chromatin condenses in chromosomes. During prophase, the nucleoli disappear and the chromatid structure of the chromosomes becomes apparent. Since each chromosome has duplicated and now consists of two sister chrom…atids, the nuclear membrane dissolves so that the sister chromatids can separate. If it didn't dissolve, they'd still be held together. ( Full Answer )
"scientist have not discovered WHY it happens" It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASE Hope this helped!!!
Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced.

The cell grows, matures, and replicates it's DNA. The cell is preparing for cell division.
A lot of things happen during mitosis. When the cell is OUT of mitosis, chromosomes are not discernible from each other ; the shapeless substance they form is called 'chromatin', and genes can be (and are) expressed at that stage. Then prior to mitosis, chromosomes duplicate (this is called the 'Rep…lication'). During mitosis now : * Prophase: Chromosomes condense into the fully discernible "X-shaped" pairs that can be ordered by size. Each "X" is actually two identical chromosome molecules bound together ; genes are not expressed in this compact form. * Prometaphase: At that stage, the nuclear membrane disappears. // It is important because chromosomes are then accessible to the microtubules network. Actually two networks form, each from a center called centriole (one for each daughter cell, diametrically opposed on each side of the mother cell). // * Metaphase: The microtubule networks expand and bind to one of the molecules of each chromosome (each branch of the "X"). * Anaphase: When citokinesis occurs they contract, thus separating each chromosome molecule from its duplicate (hopefully one chromosome molecule of each pair going in each daughter cell). * Telophase: The nucleus membrane is then reformed in the daughter cells and chromosomes go back in chromatin form. Disclaimer : the disappearance of nucleic membrane is NOT common to all eukaryota (although it is for all animals). Some species perform the whole process with an intact nuclear membrane.

Interphase is the stage in which the cell grows, matures, and replicates its DNA. It is divided into three phases - G1, S, and G2. During interphase the cell prepares itself for cell division.
The cell grows, and develops, as it doubles its size. It containsDNA structures now, called chromosomes.
In prophase, the nuclear envelope breaks down and a spindle forms between to centrioles. This is also the stage where the chromosomes are maximally condensed.
Any process that leads the cell toward appropriate division. Cells in interphase are not directly preparing for replication.
Cells do not divide during interphase. Interphase is the phase ofthe cell cycle in which cells prepare for cell division. Duringinterphase, cells make a copy of themselves and their DNA for thenext step, which is cell division that happens during mitosis ormeosis.
Interphase has 3 stages: G1, S, G2. The chromosomes are single-stranded in G1, replicate (double-stranded) in S, and prepares for mitosis (still double-stranded) in G2. So the answer is: both single-stranded AND double stranded...depending on what stage of interphase you are interested in.
During Interphase the cell grows to its mature size, makes a copy of its DNA, and prepares to divide into two cells.
the machinary required to sperate the sister chromotids (each set of DNA) is outside the nucleus, and therefore requires access to the DNA. also the nucleus is quite small, so allowing the DNA access to the rest of the cell allows for more separation (i.e. a greater distance between the two sister c…hromotids can be acheived).

The cell is prepared for division. Chromosomes become shorter and fatter and each chromosome makes an exact copy of itself forming 2 chromatids joined at a centromere
This is the stage of mitosis where the cell is not dividing, and is doing normal cell functions, such as making proteins, growth, and towards the end of interphase the cell prepares for prophase .

Cytokinesis is happenings during/after telophase. During Interphase DNA has replicated but not yet formed a chromosome, they remain chromatin until prophase where they shorten and condense to become the Chromosomes
Interpase is a part of cell division and alternates with the mitotic phase. interphase a much longer stage , which often accounts for about 90% of the cycle. It is during interphase that the cell grows and copies its chromosomes in preparation for cell division. lnterphase can be divided into subbph…ases: the G 1 , phase ("first gap"), the S phase ("synthes's"), and the G 2 phase ("second gap''). During all three subphases, the cell grows by producing proteins and cytoplasmic organelles such as mitochondria and endoplasmic recticuium. However, chromosomes are duplicated only during the S phase Thus, a cell grows ( G 1 ), continues to grow as it copies its chromomes (S phase) , grows more as it completes preparations for cell division (G2) , and di- Vides (M). The daughter cells may then repeat the cycle. During interphase , the single centrosome replicates, forming two centrosomes, which remain together near the nucleus . The two centrosomes then move apart from each other during prophase and prometaphase of mitosis, as spindle microtubules grow out from them. By the end of prometaphase, the two centrosomes, one at each role of the spindle, are at opposite ends of the cell. ( Full Answer )
The cell grows larger and increases the number of organelles in it. DNA is replicated semi conservatively. In summary, the cell prepares itself for the next nuclear division.
No, distinct nuclei begin to form during the Telophase, and Cytokinesis, the division of the cell's cytoplasm to create two distinct cells, occurs shortly after.
During interphase the cell grows, carries out metabolism, and if it will reproduce, it replicates its DNA.
nothing happens during interphase. That is when the cell starts the process of the cell cycle and goes into prophase.
In interphase he nuclear envelope binds to nucleus which contains more than one nucleolus. In the Prophase the nucleoli disappear.
Hello :) Nuclear membrane breaks right before metaphase 1 which is Prophase 1 thank U
Chromatin. The loose and, basically unwound form of chromosomes that are still wrapped is histones.
The cell grows and carries out its functions, and replicates its DNA in preparation for mitosis.

Yes, DNA replication occurs during interphase. Specifically the S stage which stands for synthesis. The replication has to occur in interphase so the cell will be ready to divide in mitosis.
The nuclear membrane breaks down during prophase, while the Deoxyribonucleic Acid (DNA) is forming into chromosomes The nuclear membrane must break down to allow the chromosomes to be pulled apart and away from the area of the former nucleus towards the pole where the daughter cell will be form…ed. If the nuclear membrane did not break down the spindle fibers would not be able to reach the chromosomes and they would not be moved towards opposite poles of the cell.

What does not occur during interphase excretion of wastes cell repair protein synthesis nuclear division?
you probably asked this a long time ago but the answer is nuclear division, because interphase is befor cell division. :)
No, cytokinesis is the last step of cytokinesis. The steps of cell division are interphase, prophase, metaphase, anaphase, telophase, and cytokinesis.

So transcription factors and RNA polymerase have access to it to induce transcription. DNA that is not transcribed in a particular cell (e.g. hemoglobin gene in nerve cells) is not unraveled as much and remains as tightly packed heterochromatin. The parts of your DNA that are actively transcribed un…ravel the most and are called euchromatin. ( Full Answer )
Because the duplicated chromosomes will need to get out of the nuclear envelope so the can go to the metaphase plate and be pulled to the poles of the cell during anaphase.
actual DNA is in scattered form but for the sake of cell division it coils and assume chromosomal shape.
There are three known steps that occur during the interphase. These steps include the gap 1, which occurs immediately after mitosis, the synthesis, and the gap 2, which is the continual growth of the cells.
Chromosomes need to double so that when the cell divides during mitosis/meiosis the daughter cells are left with the correct number of chromosomes. For mitosis, a copy of the chromosomes (DNA) is made so that when the cell divides in two - each of the new cells has the same amount of chromosomes …as the original cell. ( Full Answer )
