prophase is the first step in Mitosis. It is when the loose DNA starts to gather to form chromatid, the DNA copies itself, the spindle fibers start to form, and the cell prepares itself for cell division.

The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
What is the phase that two new nuclear envelopes form?
In the Prophase. Nuclear envelope and nucleolus disappears.
What stage of mitosis does the nucleolus disappears?
I am not 100% shure on this but i do believe it to take place during prophase
What stage mitosis is it when chromosomes shorten and thicken and the nuclear membrane begins to disappear?
In prophase stage, the replicated chromosomes condense and the nuclear envelope disappears. Earlier in prophase, chromatin visible condenses into the chromosomes.
Number of cells during prophase?
There is still only 1 cell during prophase.
When does the nucleolus begin to fade away?
Prophase.
The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
What stage occurs when crossing over occurs in meiosis?
Prophase I of Meiosis.
What is the phase that two new nuclear envelopes form?
In the Prophase. Nuclear envelope and nucleolus disappears.
During which phase does the chromatin condense into chromosomes?
The chromosomes coil up and condense during prophase
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
What is the difference between prophase mitosis and prophase meiosis?
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
What are the first steps in mitosis?
Prophase: The condensation of chromosomes; the nuclear membrane disappears; formation of the spindle apparatus; chromosomes attach to spindle fibers.
Does meiosis 2 have a prophase stage?
Yes, it does, only it is called prophase 2 or prophase II.
In what stage do the centrioles move apart?
The centrioles begin to move apart in the Prophase.
During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
In prophase do the nuclear membrane dissapears?
late Prophase
