Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain interphase and its sub-phases, relay events, checkpoints and regulation from cell biology sources, describe mitotic and meiotic interphase, and distinguish interphase from mitosis, from the G0 resting state and from interkinesis.

The longest phase of the cell cycle, between successive cell divisions, during which the cell grows, replicates its DNA and prepares to divide, comprising the G1, S and G2 sub-phases, occurring before mitosis as mitotic interphase and before meiosis as meiotic interphase, sometimes with a brief interkinesis between the two meiotic divisions; interphase is when most cellular activity and checkpoints take place.

What it is for: Not applicable; a cell cycle phase.

It can be explain the phase; relay events and checkpoints; describe variants; distinguish related phases.

Distinguishing features

Between divisions

Growth and replication

Three sub-phases

Checkpoints

What it looks like

Not a visible object; a cell with an intact nucleus and diffuse chromatin.

Physical character

share of cell cycle: about 90 percent - typical

sub-phases: G1, S, G2 list

human cell cycle: about 24 hours - cultured cells

How it is recognised

Cell cycle phase between divisions

G1, S and G2; mitotic interphase; meiotic interphase

Mitosis divides the nucleus; G0 is quiescence; interkinesis is between meiotic divisions

  • How should cell biology sources be linked?
  • How should the registry record mitotic and meiotic variants?
