The DNA of the cell must be duplicated so each resulting daughter cell has a complete copy of the DNA of the parent cell.

A duplication of the chromosomes is what must happen before meiosis can begin.
In the nucleus before cell division. The DNA is located in the nucleus to begin with, and as it is double stranded.
The daughter chromosomes begin to unwind into chromatin, the nucleolus reappears, & the nuclear evelope begins to re-form. The mitotic apparatus disassembles, thus terminating mitosis.
DNA must replicate before mitosis can begin. Mitosis is another word for cell division and so there needs to be two copies of the DNA for the two new cells.

During prophase, the chromatin fibers present in the nucleus coil tightly into observable chromosomes. The centrosomes move away from each other and spindle microtubules begin to grow from them; this marks the formation of the mitotic spindle.

DNA replicates and forms tetradβAPEX.
The primary things that happen before a blizzard are a drop in temperature and an increase in cloud cover. The sky will begin to darken as the imminent storm approaches.
Before Lexington and Concord happened before. But most major battles didn't happen til after.

Neither. 1200 am is noon, and marks the division between morning and afternoon. 12:01 is afternoon. 11:59 is before noon, or morning.
Nothing much will happen until January 2012, although candidates will try to raise money and "feel" people out before then,
