In prophase, the chromatin network begins to coil and appears as a long thread-like structures called chromosomes. Each chromosome consists of two chromatids that disappears from early prophase to late prophase. The nuclear membrane also starts disappearing in late prophase. In telophase opposite poles of the chromosomes lose their identity and nuclear membranes is formed around the daughter nuclei. Nucleolus also reappears. So, it is reverse of prophase.
