Which stage of cell cycle varies most in length?

Answer 1

There isn't a way (yet) to defined the lengths of stages in the cell cycle. One reason is because the cell cycle makes several stops/checkpoints. The G2 stage has a checkpoint/stop if DNA has not finished replicating and this will prevent the start of the M stage before completion of the S stage. Another cell cycle checkpoint occurs during the M (mitotic) stage. The cell cycle stops if the chromosomes are not going to be distributed correctly to the daughter cells. Damage to the DNA can also stop the cell cycle at the G1 stage and if damage is found then DNA repairs will start but if any kind of problem is not possible to fix than cell will automatically begin apoptosis "a.k.a. cell suicide". For adult mammalian cells, interphase "which includes three stages G1, S, and G2" lasts for about 20 hours and accounts for 90% of the cell cycle and yet embryonic cells can complete the entire cell cycle in just a few hours..

Answer 2

The stages of the cell cycle are in order as follows (not including sex cells): Interphase, Mitosis, and Cytokinesis.

Interphase is the longest stage of the cell cycle, however don't confuse the cell cycle as the same thing as mitosis. Mitosis is merely a part of the cell cycle.

The phases of mitosis are: Prophase, Metaphase, Anaphase, and Telophase. Of these phases, Metaphase is the longest.

Answer 3

each phase has certain key characteristics.

in prophase, chromatin condenses to become chromosomes.

in metaphase, a spindle forms and the sister chromatids pair up in the center of the cell.

in anaphase, the spindle starts to wrip the chromatids apart, and in telephase, the cell splits up.

Answer 4

The G1 phase of the cell cycle is the stage that varies the most in length among different cell types. This is because cells can spend varying amounts of time in G1 based on factors like their growth rate, signaling pathways, and availability of nutrients.

Answer 5

depends on the cell, and can be anywhere from a few minutes to many years or indefinitely stalled.

Answer 6

In g1 cells spend most of its time in this stage. Althought it depends on the cell type in how long it will take.

Answer 7

Interphase.

Answer 8

G1
