WebDistinct chromosomes are not visible to the microscope at this time. But, the chromatin of the nucleus (B) appears prominent after staining. A nuclear envelope (C) encloses this region of the cell. Label the Interphase diagram: 1. nucleolus, 2. chromatin, 3. centrioles, 4. cell membrane, 5. nuclear envelope. WebOnion Root Tip Lab. Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nuclear membrane dissolves, marking the beginning of prometaphase. Proteins attach to the centromeres creating the kinetochores. Microtubules attach at the kinetochores and the chromosomes begin moving.
