Nuclear envelope
Nuclear membrane and nucleolus
Cellular Division.
telophase (4th)
the nuclear envelope breaks down during prophase near the same time the chromatin condenses.
During mitosis, chromosomes are in their most condensed form during metaphase
During the interphase
"scientist have not discovered WHY it happens"It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASEHope this helped!!!
Chromosomes form during Prophase of Mitosis.
The chromosomes coil up and condense during prophase
Crossing over occurs during Prophase I of meiosis.
yes, during prophase
