hi it starts at interphase.
1. Interphase DNA has replicated, but has not formed the condensed structure of chromosome. They remain as loosely coiled chromatin. The nuclear membrane is still intact to protect the DNA molecules from undergoing mutation.

What is the result of mitosis?
The result of mitosis(or offspring)is two daughter cells.
When does mitosis begin to slow down?
At the end where it splits into two different cells
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 exactly happens in phase 4?
There are many things that happen in phase 4 of Mitosis. In phase 4 of Mitosis, the prophase chromosomes separate into pairs. Spindle fibers begin to form.
What complex of two proteins gives the ok signal for a cell to begin mitosis?
The two proteins that give the ok signal for a cell to begin mitosis are chromosomal and cell-cycle proteins. They are very useful in most of the cell activities.
What organelle divides during the process of mitosis?
the nucleus
Which cellular organelle is involved in the division of the sister chromatids during mitosis?
centromere
What organelle has two short microtubules at right angles and have an active role in mitosis?
centriole
What cell organelle is responsible for the regulation of cell reproduction in mitosis or meiosis?
squirl pune tang
Organelle composed of two short microtubules at tight angles to each other has active role in mitosis?
centriole
How Harper centrioles?
small cyclinder shaped organelle made of proteins tubes arranged in a circle aids mitosis
What organelle structures involved in mitosis in animal cells only?
In animal cells... Centrioles, asters and the spindle fibers.
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
