Interphase is not actually a resting phase. It is just called so because the chromosomes are not seen at this phase because they are in chromatin form(invisible) but actually in Interphase the cell undergoes intense chemical activity. Interphase has 3 stages:
G1: All organelles are synthesized except mitochondria and chloroplast, cell has high metabolic rate.
S: DNA replication occurs. Protein molecules called histones are synthesized n cover DNA. The cell is 4n at this stage.
G2: Mitochondria and chloroplast are synthesized and energy store of cell increases.
And yes INTERPHASE occurs first and then mitosis or meosis can occur

If a cell is not undergoing mitosis then which of the following stages is it in?
It would be in the Interphase stage. Interphase is the stage where a normal somatic cell is not undergoing mitosis and is the period of growth and DNA replication before the start of Mitosis.
In what phase of mitosis does the Majority of cell growth occur?
Cell growth occurs during interphase. Interphase prepares the cell for division by doubling the number of organelles and duplicating the chromosomes. Interphase is not actually part of Mitosis, as mitosis is strictly the dividing of the cell. Thus, no growth occurs during any of mitosis' four phases (prophase, metaphase, anaphase, telophase).
Three substages of interphase?
G I = growth phase. S = synthesis phase ( DNA replication ) G II = the second and final growth phase before mitosis.
How is meiosis 2 different from mitosis?
very little difference
The period of growth in between cell divisions is called?
It is interphase, which is divided into three stages. First is a growth stage (G1), during which the synthesis of proteins and other necessary molecules takes place and the cell becomes larger. At about mid-interphase the cell replicates its nuclear DNA (S phase; the letter stands for "synthesis"). Finally there is a second growth stage (G2).

Is interphase longer or shorter than mitosis?
Interphase is different from the division stages of meiosis and mitosis in that no division occurs at interphase. Activities that occur include increase in the size of the cell and DNA synthesis.
Three substages of interphase?
G I = growth phase. S = synthesis phase ( DNA replication ) G II = the second and final growth phase before mitosis.
Does cell growth and replication continue through the cell cycle?
No. Cell growth and DNA replication occur during interphase but do not occur during mitosis and cytokinesis.
What phase is the period of interphase when genetic information is being duplicated?
The S phase of the cell cycle (mid-interphase).There are 4 main phases. The "S phase" of the cell cycle is when the cell duplicates the genetic information, or DNA. * G1 = growth and preparation of the chromosomes for replication * S = synthesis of DNA by semi-conservative replication and duplication of the chromosome * G2 = preparation for mitosis * M = mitosis
When does the replication of DNA occur?
The DNA replicates during the S phase of interphase, after G1 and before G2, the two growth phases. Throughout interphase, the DNA is extended, and free nucleotides have access to the strands.

Does cell growth occur in interphase?
Yes. Cell growth occurs in interphase.
What is the mitosis of plant cell?
Interphase, Prophase, Metaphase, Anaphase and Telophase

What are the two main phases of the cell cycle?
The two main phases of the cell cycle are; mitotic phase, in which the cell divides into two, and inter phase, where the cell grows.
