The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is Interphase. Interphase is the first stage of the cell cycle.
Prophase
The chromosomes condense during prophase, the first stage of both mitosis and meiosis.
Chromatin
mitosis is the duplicate of chromosomes and meiosis is the reducing of chromosomes.
Chromosomes are found only in the nucleus of the cell. Although they are actually observed as chromatinthroughout most of the cell's life the chromatin does condense into chromosomes during mitosis/meiosis.
In prophase stage, the replicated chromosomes condense and the nuclear envelope disappears. Earlier in prophase, chromatin visible condenses into the chromosomes.

Chromatin
During mitosis, chromosomes are in their most condensed form during metaphase
The chromosomes coil up and condense during prophase

Chromosomes
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.

replicate or duplicate
In Mitosis, the chromosomes duplicate themselves. In Meiosis 1, they duplicate, however they do not duplicate in meiosis 2.
