While looking at a cell under a microscope you notice there is no nucleus and the chromosomes are double stranded (they have 2 sister chromatids). What phase of mitosis is

the cell probably in?

This is the Prophase. Mitotic Prophase,

Explanation:

The process  cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called  a multiplication division because two daughter cells are  form from a single  the mother cells. Each of the daughter cells can also undergo Futher divisions.

It is the second stage fist  mitotic cells division after the first phase called Interphase.

In this stage, the nuclear membrane disappear, nucleolus disintegrate and  the nucleus disappeared  This is followed  by the constriction of the chromosome to sister chromatids.

The constricted nuclear membrane leads to the releases of the chromatids This is  followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.

other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)
