NEET PG DENTAL EXAM

Detailed explanation-1: -During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.

Detailed explanation-2: -Schizosaccharomyces japonicus cells form an intra-nuclear spindle as in cells undergoing closed or partially open mitosis. However, during anaphase, the nuclear envelope ruptures as the nucleus elongates without nuclear envelope expansion.

Detailed explanation-3: -Prophase: The nuclear envelope breaks down. The chromatin condenses into chromosomes. Metaphase: The chromosomes line up along the metaphase plate. Microtubules originating from the centrosomes at the 2 opposite poles of the cell attach to the kinetochores of each chromosome.
