The cell cycle has four main parts. Growth 1, Synthesis, Growth 2, and Mitosis. If a cell is about to start mitosis, that means it has passed through the first 2 stages and is in Growth 2. Each stage has checkpoints to make sure the previous stage is completed, so all those conditions like proper nutrients, appropriate division signal, completed DNA synthesis, and large enough size are met when the cell is about to enter mitosis.
What else can I help you with?
How many cells does mitosis start with?
Mitosis typically starts with one cell that has already gone through a round of DNA replication during the S phase of the cell cycle. This cell is called a somatic cell and contains a full set of chromosomes.
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.
When does DNA replicate during mitosis?
DNA replicates during the S phase of the cell cycle, which occurs before mitosis.
In which stage of the cell cycle, mitosis or meiosis, does DNA replication occur?
DNA replication occurs in the S phase of the cell cycle, which is part of both mitosis and meiosis.
What 3 stages are replicated before mitosis?
The three stages before mitosis are the G1 S and G2 phases. In the G1 phase the cell grows, in the S phase the cell replicates its DNA, and in the G2 phase the cell grows again and replicates/ makes any organelles required for mitosis.

Describe what needs to happen in a cell before mitosis can start?
Before mitosis can start, a cell must undergo a phase known as interphase, during which it prepares for division. This involves the replication of its DNA during the S phase, ensuring that each daughter cell will receive an identical set of chromosomes. Additionally, the cell grows and synthesizes proteins and organelles necessary for the division process. Finally, the cell checks for any DNA damage and ensures it is ready to proceed to mitosis.
Does DNA replicate in mitosis?
no DNA replicates before mitosis. It replicates in the S phase of inter phase
When does DNA replicate during mitosis?
DNA replicates during the S phase of the cell cycle, which occurs before mitosis.

What are the stages in order of cell cycle?
mitosis, g1, s phase, g2
What are all the stages of cell cycle in order?
The stages of the cell cycle are G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). G1 involves growth and normal cell functions, S phase is when DNA replication occurs, G2 prepares for cell division, and M phase involves cell division where mitosis and cytokinesis occur.
When does DNA copy itself in mitosis?
DNA copies itself during the S phase of the cell cycle, which occurs before mitosis.
During what phase of mitosis is the DNA duplicated?
During the S phase of the cell cycle, which occurs before mitosis, the DNA is duplicated.
What are three stages of the cell cycle and the four phases of mitosis?
The three stages of the cell cycle are interphase, mitosis, and cytokinesis. The four phases of mitosis are prophase, metaphase, anaphase, and telophase. In mitosis, the cell's nucleus divides into two identical daughter nuclei.
