What phase is a new nuclear membranes are complete in the cells?
New nuclear membranes are completed during the telophase phase of mitosis. In this phase, the separated chromosomes reach the opposite poles of the cell, and the nuclear envelope reforms around each set of chromosomes, creating two distinct nuclei. This marks the final stage of cell division before the cytoplasm divides in cytokinesis.
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 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.
Why must the nucleus divide before the cytoplasm?
During Mitosis, it isn't the nucleus itself that divides it is the chromatin inside the nucleus that duplicates during Prophase. This is so the new cells being created each have the correct amount of DNA for normal cell use.Because the nucleus is like the center of the cell. It tells the cell what to do and basically controls it.-6th grade science teacher
Where does DNA replication take place in eukaryotes?
This occurs WITHIN the DNA molecule [large individual=chromosome] AS IT exists in a Cell's nucleus. Before any synthetic activity may be performed upon nuclear chromosomal DNA, it must first be decondensed, or dispersed into Chromatin within the Cell's Nucleus.

Two nuclear membranes must form before telophase, as the nuclear envelope reforms around the individual sets of chromatids within each daughter cell.
What part of each cell must disappear between step 1 and step 2 to release the paired chromosomes?
The nuclear envelope must disappear to release the paired chromosomes during cell division. It breaks down during prophase to allow the chromosomes to interact with the spindle fibers before moving to opposite poles of the cell.
This nuclear structure may be visible during interphase?
The nucleolus is a nuclear structure that may be visible during interphase. It is involved in ribosome production and is typically visible as a dense, dark area within the nucleus during periods of high ribosomal activity.
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 is mean by open mitosis and closed mitosis?
Open mitosis occurs in most animal cells where the nuclear envelope breaks down ("opens" before the chromosomes separate. Closed mitosis occurs in some fungi, such as Aspergillusand Saccharomycesspecies, where the chromosomes divide within an intact ("closed") cell nucleus.
What do you stick on a letter before mailing it?
you stick it on an envelope before mailing it
What happens to the info before the cell divides?
Your DNA is copied into the new cell every time it divides
What is the best way to seal an envelope without using envelope gum?
The best way to seal an envelope without using envelope gum is to use a wet sponge or cloth to moisten the adhesive strip on the envelope flap before pressing it down to seal it shut.
How does the absence of a nuclear envelope in the prokaryotes prevent prokaryotes from controlling gene expression by modifying RNA after transcription?
In eukaryotes, mRNA is processed inside the nucleus before being shipped out into the cytoplasm for translation. Specifically, a strand of pre-mRNA (or immature mRNA) has a GTP cap added to its 5' end, a poly-adenine tail added to its 3' end, and it has its introns spliced out. Since prokaryotes don't have nuclear envelopes, they don't have an area to do this.
