In which phase do chromosomes condense
WebChromosomes condense and become visible by light microscopy as eukaryotic cells enter mitosis or meiosis. During interphase (G1 + S + G2), chromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes). In G1, each chromosome is a single chromatid. http://fort.lepak.com.my/why-do-chromosomes-condense-during-prophase/

Mitosis has four sequential stages: prophase metaphase anaphase and telophase. In prophase each chromosome becomes condensed and more visible and there is the breakdown of the nuclear membrane and appearance of spindle fibers.
