At the end of prophase all of the chromosomes(chromatids joined at the centromere) are now floating around the cells and the spindle fibers are formed. Then you go into Metaphase where the chromosomes line up in the center of the call and the centromeres attach to the spindle fibers.
Hope that helped!:)
At the end of Prophase, the nuclear membrane has completely disappeared, the chromosomes are fully condensed and visible, and the spindle fibers have attached to the kinetochores of the chromosomes. The cells are preparing for metaphase, the next stage of mitosis.
In the stages of Mitosis Prophase is step one. It is then immediately followed by metaphase, anaphase, and telophase without stopping. This entire four stage process is completed very quickly. In most cases, it is done within an hour.
prophase occurs after interphase and before metaphase. It is when the genetic material condenses into chromosomes, and the spindle apparatus (fibers) are created.

But the end of prophase each of the following has occurred except?
lining up of chromosomes in the cell
Following is a phase of mitosis?
Mitosis has six different phases in the cell division cycle including intraphase, prophase, prometaphase, metaphase, anaphase and telophase. Prometaphase occurs right after the end of prophase.
What stage occurs when crossing over occurs in meiosis?
Prophase I of Meiosis.
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

How is telophase the reversal of prophase?
Telophase and prophase are two distinct stages of mitosis. Telophase involves the separation of sister chromatids to opposite poles of the cell and the formation of new nuclear envelopes around the separated chromosomes. This is different from prophase, which involves the condensation of chromosomes, breakdown of the nuclear membrane, and formation of the mitotic spindle. In telophase, the events aim to reverse the processes that occurred in prophase to prepare for cell division.
What happens in prophase of mitosis?
In prophase chromatin condenses, spindle fibers form a bridge from one end of the cell to another, and the nuclear membrane starts to break down.
What stage occurs when crossing over occurs in meiosis?
Prophase I of Meiosis.
What is the phase that two new nuclear envelopes form?
The phase where two new nuclear envelopes form around the two sets of daughter chromosomes is called telophase. In telophase, the nuclear membrane reforms around the chromosomes and the nucleoli reappear. This marks the end of nuclear division in cell mitosis.
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 do you start with in meiosis What do you end with?
you start with a cell in interphase and end with a cell that has reproducedthat is not trueYou start with Prophase and end with telophase, or 4 cells (meiotic products)
What major event happens just before prophase 1 of meiosis but does not occur before prophase 2?
Crossing over of genetic material occurs just before prophase 1 of meiosis, where homologous chromosomes exchange segments. This event does not occur before prophase 2 because homologous chromosomes have already separated during meiosis I.
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.
The first phase of mitosis is called?
The first phase of mitosis is called prophase. During prophase, the genetic material condenses into visible chromosomes, the nuclear membrane breaks down, and the mitotic spindle begins to form.
