What event must occur outside the nucleus before mitosis can begin?

Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.

What happens before meiosis begin?
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
Which phase of mitosis do a new nuclei begin to form?
telephase
Animal cells begin to pinch in what phase of mitosis?
prophase
What is the phase of mitosis when chromosomes become visibly shortened and thickened?
Prophase
Is the first phase of mitosis in which chromosomes condense and spindle microtubules begin to form.?
the phase of mitosis when chromosimes are ligned in the middle of the cell
What cell breaks down nucleus in the mitosis?
There is not a particular "cell" that breaks down the nucleus during the cell process of mitosis. However, the nucleus does begin to break down in the phase known as prophase/prometaphase.
Why is it important that DNA replicates before the process of mitosis?
DNA must replicate before mitosis can begin. Mitosis is another word for cell division and so there needs to be two copies of the DNA for the two new cells.
What happens before meiosis begin?
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
Where does Duplication of DNA takes place?
In the nucleus before cell division. The DNA is located in the nucleus to begin with, and as it is double stranded.
What must happened before mitosis can begin?
The chromosomes must be duplicated. the real answer: DNA replicates and forms tetrads
What part of the cell cycle occurs before mitosis can begin?
Interphase is the part of the cell cycle that occurs before mitosis can begin. Interphase is made up of the G1, S, and G2 phases. These phases of Interphase prepare the to-be-diving cell by increasing the cell size and synthesizing the DNA within that cell.
How does the cell prepares for mitosis?
A cell gets ready for mitosis through replication. Before mitosis can begin, the nucleus must make a copy of its chromatin. This ensures there is two complete sets of deoxyribonucleic acid (DNA.) This step is known as replication. When this stage occours, chromatin cannot be seen with a light microscope. The replication chromatin coils up to form double stranded chromosome, which are joined in the middle by a centromere. After replication, two complete sets of DNA are bundled up together as double stranded chromosomes. The nucleus, or "brain", of the cell is finally ready for mitosis to begin.
In which step of mitosis do the fiber begin to disappear?
The spindle fibers begin to disappear in Telophase
What happens to the chromosome of a cell in order for mitosis to begin?
they have to split
Which phase of mitosis do a new nuclei begin to form?
telephase
What is the result of mitosis?
The result of mitosis(or offspring)is two daughter cells.
Animal cells begin to pinch in what phase of mitosis?
prophase
