prophase consist of G1, S, G2 phase during which DNA replicates (it is copied) and cell grows (to double size)

∙ 13y agoDuring prophase, the DNA condenses to form chromosomes and the nuclear membrane dissolves. The nucleolus also dissolves.

What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
In mitosis each daughter cell ends up with the same number of chromosomes as the mother cell.
Number of cells during prophase?
There is still only 1 cell during prophase.
Chromatin threads change to dense rods during the process of?
Chromatin changes to thick rods called chromosomes during anaphase. During anaphase the centromeres divide and are pulled apart by the spindle fibers. They then move to opposite ends of the poles.
When during the cell cycle are chromotomes visible?
During Interphase.......NO During Mitosis........YES * assuming you mean visible through a microscope
When in the cell cycle does the nuclear membrane begin to fade?
In mitosis the nuclear envelope begins to break in prophase. In meiosis the nuclear envelope begins to break in prophase 1.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
In mitosis each daughter cell ends up with the same number of chromosomes as the mother cell.
When during the cell cycle are chromosome visible?
During Prophase
When does the process shown occur in the cell cycle?
In 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 what part of the cell does the replication occur?
DNA replication occurs during Interphase. This is not normally part of the cell division cycle but interphase must occur before subsequent stages such as prophase and metaphase can occur.
Number of cells during prophase?
There is still only 1 cell during prophase.
In what phase does chromosomes condense and become visible?
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
What events occur during prophase?
The nucleoli disappears; the nuclear membrane breaks down; the mitotic spindle appears and the centrioles begin moving towards opposite ends of the cell.
When does crossing over occure?
prophase I
Can chromosomes be seen in a cell that is observed in prophase?
Yes. During prophase the chromosomes condense to prepare for cell division.
What phase in the cell cycle dissolves the nuclear membrane?
The Nuclear membrane dissolves during prophase
Does condensation of the chromosomes occur during mitosis?
Yes it occurs during prophase, the first phase of mitosis. This is the only time when we can see the physical shapes of the cell's chromosomes.
