Interphase, because during pro phase they become visible so that means in interphase they were not visible.
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes 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.
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
1 Prophase - DNA coils up , chromatids form and chromosomes become visible, nuclear envelope dissolves, and spindle fibers form.
Interphase
During Prophase
Chromatids are visible during the Prophase of the Cell Cycle, as the chromosomes which chromatids are formed from condense, thus making them visible.
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
During Interphase.......NO During Mitosis........YES * assuming you mean visible through a microscope

1 Prophase - DNA coils up , chromatids form and chromosomes become visible, nuclear envelope dissolves, and spindle fibers form.
The chromosomes are replicated during interphase.
The DNA is visible and packaged as chromosomes.
mitosis particularly prophase
Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.
