Which stage of the cell cycle lasts longer?

The G1 phase of interphase generally lasts the longest because that is the stage that the cell spends most of its "life". This is where cell growth and metabolism occurs; the cell is doing whatever job it does for the organism. It sits in G1 until there is some kind of signal telling it it must divide again. If this is the kind of cell that doesn't divide again once it is made, we call that phase G0 (zero) and that is like sitting in G1 until the cell dies.


I don't know for sure, but choosing between prophase, metaphase, anaphase and telophase, I think it takes longer for the chromosomes to condense during prophase than the other phases. If you consider interphase a phase of the cell cycle (during which DNA or chromosome synthesis ocurrs), it would be the longest.

Ron Baker, Ph.D.

Interphase is by far the longest stage of the cell cycle. You can think of interphase as being the time when a cell is going about its usual business. Mitosis, then, is a brief pause in that business to take care of cell division.
