How does the nuclear envelope allow for cell reproduction?
At the time of nuclear division the nuclear envelope get disintegrated to provide enough space to the chromosomes to move at two poles of the spindle. When the division is complete the nuclear envelope organizes again around these daughter nuclei.
Where in the nucleus are the chromosomes located?
They are located in the center of the nucleus.
What happens to the structures in the nucleus in each stage prophase plus?
In Mitosis, there are four stages involved in the separation of chromosomes. It produces two identical sets of chromosomes in two nuclei.1. Prophase: The double-stranded chromosomes condense, and the nuclear membrane around them degenerates.2. Metaphase: The chromosomes line up in the middle (equator) of the cell. The centrioles, which produce spindle microtubules, divide and move to either end of the cell. The spindle fibres form.3. Anaphase: Sister chromatids* are pulled apart by the spindle fibres.4. Telophase: The chromosomes are at either end of the cell, and new nuclear membranes start to form around them.*one of two identical copies/strands of DNA which make up a chromosome. They are generally 'X' shaped and joined at a point called the centromere.
What in a cell holds the nucleus together?
The nuclear membrane around the chromosomes.
Where is the DNA that the nucleus contains?
It is situated in the Nucleolus of a cell. There is the middle Nucleus and around the nucleus are thread like structures known as chromosomes which carry Hereditary characteristics to the next generation and these chromosomes contain DNA.
What is miotic spindle?
The miotic spindle moves the chromosomes around in the cell during prophase. The miotic spindle is formed by excess parts from the dismantled cytoskeleton.The spindle is initially setup outside the nucleus. p.s- im in ap biology so u can trust my answer :)

What holds chromosomes in place?
The nucleus has a double membrane, often referred to as the nuclear envelope. This membrane contains small gaps called nuclear pores. However, DNA is far too large to be able to pass through the nuclear pore. This means that, although chromosomes are free to move around in the nucleus, they are always kept inside the nucleus.
What does a nucleus do in a mitosis of a single cell?
During the first stage of mitosis, prophase, the nucleus and nucleolus disappear. Mitosis then proceeds into metaphase and anaphase. Then during telophase, the nuclei reappear in the two cells and finally the cells split apart from each other by a process known as cytokinesis.

What part of the cell divides during mitosis?
here are the steps of a cell producing another cell interphase: cell matures, makes a copy pf the dna prophase: chromatin become chromosomes, spindle form a bridge Metaphase: the chromosomes line up across the cell, each chromosomes attaches to a spindle at its centrolmeres anaphase: the centromeres, each chromaid becomes new chromsome, they move to oppisite ends of the cell, the cell is pushed telophase: chromosomes begin to stretch, a new nuclear envelope forms around each region of chromosomes cytokinesis: the cell splits, each daughter cell has an identical set of chromosomes and same dna
A structure found in the nucleus that is made of DNA?
Chromosomes - structures composed of DNA and proteins found in the nucleus of eukaryotic cells. Chromosomes carry the genetic material. Chromosomes - structures composed of DNA and proteins found in the nucleus of eukaryotic cells. Chromosomes carry the genetic material.

What is is mitosis?
Mitosis is the scientific term for nuclear cell division, where the nucleus of the cell divides, resulting in two sets of identical chromosomes. Mitosis is accompanied by cytokinesis in which the end result is two completely separate cells called daughter cells. Also it is the second part of the cell division process.Short answer: asexual cell division where two identical daughter cells are formed.Phases of mitosis:There are four phases of mitosis: prophase, metaphase, anaphase and telophase. The first phase of mitosis is prophase. In this phase the chromosomes which are normally spread throughout the nucleus begin to condense into a tight ball. The DNA molecules of the chromosomes begin to interact with enzymes and proteins that assist in the replication of the genes. The compact coiling of the chromosomes at this stage of mitosis is called mitotic chromosomes. Nearing the end of prophase, the material enclosing the nucleus and the cytoskeleton disappears. The cytoskeleton is transformed into what is called a spindle apparatus which works to pull the duplicated chromosomes apart during the anaphase.The second phase of mitosis is metaphase. In this phase the chromosomes of the dividing cell begin to line up and are coordinated with the spindle apparatus. The soon to be divided chromosomes are symmetrically positioned on the metaphase plate typically at the equator of the parent cell.Anaphase is the third step of mitosis. Abruptly the spindle apparatus pulls the two identical sets of chromosomes apart from one another. Each new set of chromosomes is moved to opposite spindle poles. These two sets of chromosomes will soon develop into the nuclei of two daughter cells perfectly identical to each other as well as identical to the parent cell.The final stage of mitosis is telophase which means end. Telophase is best described as the opposite of prophase. As the chromosomes begin to move toward the spindle pole they start to uncoil around the vaginal area and spread out. Then the spindle apparatus made of a huge masculin penis the former cytoskeleton is deconstructed. Finally the nuclear envelope or membrane is formed around the chromosomes. Although this is the last phase of mitosis, telophase will not be complete until cytokinesis has been carried out. Cytokinesis is similar to mitosis except it involves the cell's cytoplasm and organelles where mitosis is the division of the nucleus or control center of the cell. Once mitosis and cytokinesis are properly completed there are two new functioning cells.
