During which phase of mitosis do the nuclear membrane, nucleolus, and nucleus dissolve?
metaphase
prophase
anaphase
telophase

prophase

Explanation:

It is prophase of mitosis during which nuclear membrane, nucleolus, and nucleus dissolves.

Mitosis is characterized by 4 stages which are mentioned as under:

(1) Prophase

(2) Metaphase

(3) Anaphase

(4) Telophase

Prophase is the first stage of mitosis in which two major events occur. In this stage particularly, the nuclear membrane breaks down and nuclear envelop disappears. Apart from this, the chromatin which is present inside the nucleus of the cell starts to condense to become chromosome which unlike chromatin is a thick and clearly visible structure.

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.
