Question

When the M phase begins during the cell cycle, it starts with____.

Answer 1

Prophase. The m phase consists of prophase, prometaphase, metaphase, anaphase, and telophase.

Answer 2

Answer:

-Prophase.

Explanation:

Cell cycle involves a series of events that leads to formation of two daughter cells by division of a parent cell. It can be divided into two phases, interphase and mitotic phase (M phase)

The M phase involves division of nucleus and cytoplasm to produce two daughter cells. It is divided into prophase, metaphase, anaphase, telophase and cytokinesis.

Hence, the first stage of M phase is prophase, in which condensation of chromosomes begins, nuclear membrane disintegrates, and nucleolus starts to disappear.

Thus, the correct word to be fill in the blank is 'prophase
