Question

Which phase is the longest in Mitosis and WHY? Please EXPLAIN WHY either:prophase,metaphase,anaphase or telophse is the longest.(please people interphase is NOT part of mitosis!!! it is part of the cell cycle!!!).

I am willing to give the MAXIMUM amount of points that i can for the best explanation....Thank you very much.

Answer 1

Prophase can be the longest phase of mitosis. Condensing the chromatin takes a lot of resources (winding up DNA into tight balls around the histones, etc). Plus, different cells have different numbers of chromosomes. For example, humans have 46, but other species like algae can have over a hundred chromosomes. So you can see that the process of prophase could be very long for some.

Answer 2

Prophase is the longest phase of Mitosis.  During this phase the nuclear membrane disintegrates and the nucleolus disappears.  The chromosomes condense.  The formation of mitotic spindles occur in prophase and Kinetochores mature and attach to the spindle.  These processes take time and are critical for the continuation of cell division, which is why this phase takes the longest.  

Answer 3

The longest is prophase.  During prophase, the cell begins to condense its DNA into chromosomes and get everything ready for mitosis.  I believe prophase can last up to 24 hours, much longer than the rest of cell division.
