Telophase
Verified step by step guidance1
Understand the role of the nuclear envelope during mitosis. In prometaphase, the nuclear envelope breaks down to allow spindle fibers to attach to chromosomes.
Identify the phase of mitosis where the nuclear envelope reforms. This is the phase where the opposite of prometaphase occurs.
Recall that during telophase, the nuclear envelope reassembles around the separated sets of chromosomes, effectively reversing the breakdown that occurred in prometaphase.
Compare the characteristics of telophase with those of prometaphase to confirm that telophase is indeed the phase where the nuclear envelope reforms.
Conclude that telophase is the phase of mitosis that is essentially the opposite of prometaphase in terms of the nuclear envelope.
