What phase of mitosis is there a nuclear envelope reforms around each cluster of chromosomes?
The phase of mitosis in which the nuclear envelope reforms around each cluster of chromosomes is called telophase. During this stage, the chromosomes begin to de-condense back into chromatin, and the nuclear envelope reassembles, resulting in the formation of two distinct nuclei in the daughter cells. This marks the end of mitosis, leading into cytokinesis, where the cell divides into two separate cells.

Which is the phase where a nuclear envelope re-forms around each cluster of chromosomes?
telophase
When are chromosomes completely separated in their own nuclear envelope?
Chromosomes are completely separated into their own nuclear envelope during the final stage of mitosis called telophase. During this phase, the separated sister chromatids reach opposite poles of the cell, and the nuclear envelope reforms around each set of chromosomes, resulting in two distinct nuclei. This process signifies the conclusion of mitosis and leads to cytokinesis, where the cell divides into two daughter cells.
What cellular parts disappear and what parts reappear at this stage of mitosis?
During the prophase stage of mitosis, the nuclear envelope disappears, and the nucleolus fades from view. The chromatin condenses into visible chromosomes, which consist of two sister chromatids joined at the centromere. As mitosis progresses into metaphase, the spindle fibers emerge, attaching to the centromeres of the chromosomes. The nuclear envelope will reappear in the later stages of mitosis, specifically during telophase.
What phase of mitosis has no clear nucleus?
The phase of mitosis that has no clear nucleus is called prometaphase. In this phase, the nuclear envelope breaks down, allowing the chromosomes to become more condensed and visible, but the formation of the new nuclear envelope has not yet occurred.
The events of prophase seem to be opposite of those that occur during what phase?
The events of prophase in mitosis, such as condensation of chromosomes and breakdown of the nuclear envelope, are opposite to those that occur during telophase, where chromosomes decondense, and the nuclear envelope reforms.
What stage does the nuclear envelope reform around the chromosomes?
The nuclear envelope reforms during telophase, which is the final stage of mitosis. As the chromosomes arrive at the two poles of the cell, a new nuclear envelope starts to form around each set of chromosomes, separating them into two new nuclei.
Which phase does the nuclear membrane form around the chromosomes?
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
Which is the phase where a nuclear envelope re-forms around each cluster of chromosomes?
telophase
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.
When in mitosis would you see two nuclear envelope forming around each set of chromosomes?
Telophase
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 dissolves during mitosis?
During mitosis, the nuclear envelope dissolves to allow the chromosomes to separate and move to opposite poles of the cell. This dissolution is necessary for the proper segregation of genetic material during cell division.
What stage do the Chromosomes form chromatin and the nuclear envelope reforms during?
The chromosomes form chromatin and the nuclear envelope reforms during telophase of mitosis. Telophase marks the final stage of cell division, where the nuclear envelope reassembles around the separated daughter chromosomes, and the chromatin begins to relax back into its less condensed state.
What stage of mitosis where nuclear envelop disappears and the chromosomes form?
stage of mitosis when nuclear envelop disappears and the chromosomes form is the "PROPHASE"
What stage mitosis is it when chromosomes shorten and thicken and the nuclear membrane begins to disappear?
The stage of mitosis where chromosomes shorten and thicken and the nuclear membrane begins to disappear is prophase. During prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, allowing the chromosomes to interact with the spindle fibers.
What phase does the nuclear envelope reform?
The nuclear envelope reforms during telophase, which is the final stage of mitosis. In telophase, the nuclear membrane and nucleolus reappear, and the chromosomes begin to decondense back into chromatin.
When are chromosomes completely separated in their own nuclear envelope?
Chromosomes are completely separated into their own nuclear envelope during the final stage of mitosis called telophase. During this phase, the separated sister chromatids reach opposite poles of the cell, and the nuclear envelope reforms around each set of chromosomes, resulting in two distinct nuclei. This process signifies the conclusion of mitosis and leads to cytokinesis, where the cell divides into two daughter cells.
