Prophase
Interphase as they become decondenced
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye
During prophase, the first stage of mitosis, the chromosomes become visible as distinct structures. The nuclear envelope also now breaks down, and a spindle forms.
double chromosomes first become visible in which step of mitosis?
It actally spelt prophase...1. The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.2. The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over.
Interphase as they become decondenced
Chromosomes first become visible during prophase of mitosis when they condense and coil up tightly. This allows them to be easily seen under a microscope as separate structures.

during prophase
double chromosomes first become visible in which step of mitosis?
It is during the prophase in which chromosomes first appear to be duplex structures.Each cell in a person typically has 23 pairs of chromosomes.
Interphase and Telophase
probably Telophase
They are visible during mitosis. During Prophase the DNA is compacted into Chromosomes while the intermediate filaments that make up the Nuclear Envelope are phosphorylated and it falls apart. Leaving behind the chromosomes, very easy to see throughout prophase, metaphase, anaphase and telophase (Until the nucleus reforms in both daughter cells and the chromosomes de-condense). Chromosomes are easy to see by definition, their name in greek literally means colored bodies, this mostly because the guy that saw them first had no idea what they were.
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.
