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. WebChromatids in Meiosis. Meiosis is a form of cell division that creates gametes, or sex cells (eggs or sperm).
