Early in mitosis, the nucleus, nucleolus, and nuclear envelope begin to dissolve in preparation for cell division. in which stage of the cell cycle is this process reversed?

The correct answer is telophase.

The mitosis is divided into four phases, these are prophase, metaphase, anaphase and telophase.

The prophase is the first stage, in which the nuclear membrane, nucleolus begin to disappear and the genetic material is condensed in the form of chromosomes. The nuclear membbrane and nucleolus are absent till the late anaphase.

In the telophase, the nuclear envelope and the nucleolus begin to form again, teh chromosomes are decondensed and the nucleus is formed again. So, the process, which occur in the early mitosis is reversed in this phase.
