The diagram shows the stages of the eukaryotic cell cycle.

which stage is labeled e in the diagram?

mitosis
interphase
s phase
g0 phase

The right answer is interphase.

In both eukaryotic and prokaryotic cells, the interphase is the period of the cell cycle that is characterized by an increase in cell volume, the cell transcribes its genes and the chromosomes are duplicated. It can be subdivided into several phases:

* phase G1 (growth or gap), during which the cell grows and performs the functions for which it is programmed genetically: biosynthesis of proteins, etc. It is during this phase that the young, freshly divided daughter cells grow to their final size.

* phase S (of the English synthesis, because of the synthesis of new DNA molecules), during which the chromosomal material is doubled by DNA replication. This is called chromosome duplication.

* phase G2, where the cell prepares to divide into two daughter cells. At the end of this phase, each chromosome is perfectly identical to its homolog in terms of morphology and from the point of view of the genes present, but each gene is not necessarily identical to its homologue, since generally several alleles exist.

** There is also the G0 phase, which is one of reproductive senescence. It is a possible exit from the control point at the end of G1, an alternative to the continuation of the G1 phase and the transition to the S phase. The G0 phase can be temporary or permanent and it is often induced by unfavorable conditions.

The correct answer would be interphase.

The cell cycle is mainly divided into two phases: mitosis (M) and interphase.

Interphase is the phase in which a cell spends most of its time. It is the phase of growth and DNA replication.  

It can be sub-divided into three stages:

Letter D represents mitosis (M) phase in which the actual division of the cell takes place.
