Chromosomes condense and become visible. Nuclear envelope and nucleolus disperse. Spindle apparatus forms.
The mitotic spindle forms. Apex
During prophase the chromosomes are identical chromatids connected at the center by a centromere, forming a X-shaped object. The distinguishing feature of prophase is the setup of the mitotic spindle, which is used to maneuver the chromosomes about the cell. The spindle is formed by excess parts from the dismantled cytoskeleton. The spindle is initially setup outside the nucleus.
The cell's centioles are duplicated to form two pairs of centrioles. Each pair becomes the part of the mitotic center which forms the focus for an array of microtubules, called the aster. The two asters lie side by side close the the nuclear envelope. Near the end of prophase the asters pull apart and the spindle is formed.
nuclear envelope breaks down and strands of chromatin forms into chromosomes.
During prophase, chromosomes become more coiled and can be viewed under a light microscope.
I have no clue what happen in this thing.
"scientist have not discovered WHY it happens"It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASEHope this helped!!!
There are five substages to prophase I. Genetic exchange happens during the fourth stage, Diplonema. This process is also called crossing over.
come on people im in grade ten and i am looking for answers signed Will Pew Dr.G Williams high school
Prophase is one of the stages in the process of mitosis, the stages of mistosis are : 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase. So metaphase, anaphase, and telophase are what happends in mitosis and does not happen in prophase. And what happens in prophase that does not in mitosis is that the sister chromatids that were formed during interphase have shortened and thickened and are now visible with a light microscope.
yes, during prophase
During mitosis, chromosomes are in their most condensed form during metaphase
Prophase.
moving apart
nothing happens during interphase. That is when the cell starts the process of the cell cycle and goes into prophase.
Prophase I
prophase, metaphase, anaphase, telophase (including cytokinesis)
prophase, metaphase, anaphase, telophase (including cytokinesis)

Chromosomes form during Prophase of Mitosis.
