TelophaseTelophase. The spindle disappears, a nuclear membrane re-forms around each set of chromosomes, and a nucleolus reappears in each new nucleus.
Answer and Explanation: The nuclear envelope reforms during the phase of mitosis called telophase.
Answer and Explanation: During prophase in mitosis is when the nuclear envelope and nucleoli dissolve.
During telophase, the nuclear envelope reforms on the surface of the separated sister chromatids, which typically cluster in a dense mass near the spindle poles (Fig. 44.18).
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth).
The phase of mitosis during which the nuclear envelope fragments and the nucleoli disappear is called: B) prophase.
the nuclear membraneTelophase. Now that the chromosomes are separated, two nuclei are formed. The spindle fibers disappear; the chromosomes uncoil and become spaghetti-like chromatin again, and the nuclear membrane reappears.
Prophase. Prophase is the first phase of mitosis, when the centrosomes begin moving toward opposite poles and the nuclear envelope breaks up.
