- The DNA
- All the organelles.
The DNA doubles during the interphase and coils during prophase of mitosis.
All the organelles are doubled, although mitochondria divide independently, which is another evidence of endosymbiotic theory.

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.
What happends during interphase?
During Interphase the cell grows to its mature size, makes a copy of its DNA, and prepares to divide into two cells.
What two features are visible in the nucleus during interphase?
nuclear membrane and nucleolus
When does a chromosome go from one chromatid to two sister chromatids?
During S of interphase.
The cell cycle is broken into what two steps?
M-phase and interphase M-phase and interphase M-phase and interphase M-phase and interphase
During what phase of the cell cycle does DNA replication occur?
At mid-interphase.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.During division (M phase) the DNA is condensed, so that the chromosomes are short, compact, and easily moved to the poles of the spindle.
What phase is when chromosomal material replicates?
Chromosomes are replicated during DNA replication, which occurs during interphase.
What is it called between one mitosis and another mitosis?
The period between two mitotic phases in a cell is known as interphase. During interphase, a cell carries out its metabolic processes and prepares to divide.
What phase does chromosomes first appear to be double?
It is during the prophase in which chromosomes first appear to be duplex structures.Each cell in a person typically has 23 pairs of chromosomes.
How is meiosis 2 different from mitosis?
very little difference
What stage of the cell cycle is a cell's DNA copied?
The stage in the cell cycle where DNA is replicated is actually in interphase, before the nuclear membrane dissolves in prophase. * The DNA is replicated at mid-interphase (in the S phase), between the two growth phases (G1 and G2). So replication precedes division by several hours in a typical cell.
When is DNA replicated in the cell cycle?
DNA replication occurs during the S stage of interphase. Interphase is the stage between two mitotic or meiotic divisions. It can be slpit into three stages:G1, S and G2. During G1 (gap 1), cells grow and build up ATP on preparation for DNA replication. During the S (synthesis) phase the DNA is replicated. During the G2 phase the cell prepares itself for the process of cell division (mitosis or meiosis).
