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?

Mitosis is the process by which a single parent cell divide into two identical daughter cells. The process occurs in five stages, which are: interphase, prophase, metaphase, anaphase and telophase. The processes that occur in the early part of mitosis are usually reversed at the telophase stage, which is the last stage of the process. At the telophase stage, the nuclear membrane and the neucleoi reappear and the chromosome begins to condense.

The correct answer would be the telophase of mitosis.

Mitosis or M-phase of the cell cycle is the phase in which actual cell division takes place.

It is sub-divided into four stages:

1. Prophase:

Early prophase:

Late prophase or prometaphase:

2. Metaphase: All chromosomes are aligned at the center forming a metaphase plate. In addition, two kinetochores of each chromosomes are attached to the microtubules extending from opposite spindle fibres.

3. Anaphase: The sister chromatids of the chromosome are pulled towards opposite ends of the cell. Also, the cell elongates which help in division.

4. Telophase: It is exactly opposite to what happens in the prophase. The mitotic spindle break down, nuclear membrane and nucleus reappear, and chromosome again decondense to form chromatin fibres.

Cytokinesis results in the formation of two daughter cells.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
