WebAlthough chromosome architecture in early prophase of meiosis seems similar to mitosis in principle, there is no equivalent stage during transition to metaphase I when chromosomes condense to a much higher degree and show a characteristic "smooth" surface. No indication was found for helical winding of chromosomes either in mitosis or in meiosis. 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.
Web3 jan. 2024 · Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible.
