उत्तर
The phase of karyokinesis which is almost the reverse of prophase is telophase.
Explanation:
Telophase is the phase of karyokinesis (the division of the cell nucleus) that follows prophase. The nuclear envelope reformation that distinguishes it from prophase, which also involves the condensation and collapse of the nuclear envelope, is considered to be the opposite.
