ViviBefore the Mitosis can begin, there are several things that must happen to a cell. First of all, the cell must be first be grown to twice the regular size. Once that's done, it moves on and copies all the chromosomes so they can be pulled apart and be even in both cells. Then the cell replicates all of its organelles, so each of the daughter cells will be sufficient in organelles. Now, it is ready to go into prophase, which is the first stage in mitosis,
the chromosomes must be duplicated.

What stage of mitosis does replication happen in?
Replication does not take place during mitosis. It takes place before meiosis begins.
What only takes place in reproductive organs mitosis or meiosis?
is mitosis or meiosis used to make body cells
Which phase does the preparation for mitosis occur?
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. Chromosomes will align, separate, and move into new daughter cells during mitosis. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.
What happens in the s phase that is essential for mitosis to occur?
In the S phase of the cell cycle, DNA replication takes place, resulting in the synthesis of identical copies of each chromosome. This is essential for mitosis to occur because each daughter cell needs to receive a complete set of chromosomes. Without the S phase, there would not be enough genetic material to distribute to the daughter cells during mitosis.
Where does light reaction occur in a of the chloroplast?
It takes place on thylokoid membranes.Dark reaction takes place in stroma.
