Prophase what happens
Prophase (from Ancient Greek προ- (pro-) 'before', and φάσις (phásis) 'appearance') is the first stage of cell division in both mitosis and meiosis. Beginning after interphase, DNA has already been replicated when the cell enters prophase. The main occurrences in prophase are the condensation of the chromatin reticulum and the disappearance of the nucleolus. WebbHow do the events that occur in interphase prepare the cell for prophase? In prophase, the chromosomes begin to become more visible whereas the chromosomes are formed …
