Chromosomes replicate during the 'synthesis' phase of the cell cycle. Its also simply called the 'S phase'.

prophase = organization
interphase= duplication of cellular material (organelles, chromosomes, etc.)...for mitosis; specifically the s-phase
for meiosis, um.....same b/c during interphase II there's no reproduction of chromosomes, which yield haploid cells.
sorry I took bio two yrs ago so I can't remember the details to comment further, but I'm 95% sure.

Chromosomes are doubled in both meiosis and miosis.
They are doubled temporarily and then they are either decreased to half such as in meiosis or go back to the same in miosis. Meiosis is for making reproductive gametocytes. Miosis is for making new or replacement cells. E.g. skin is always sluffing off and being replaced.
I guess this is called DNA synthesis
Just before cell division (and after DNA synthesis), the chromatin condenses further into individual metaphase chromosomes.
Also is called Cell Growth
The term cell growth is used in two different ways in biology.
When used in the context of reproduction of living cells the phrase "cell growth" is shorthand for the idea of "growth in cell populations by means of cell reproduction." During cell reproduction one cell (the "parental" cell) divides to produce two daughter cells.
In other contexts, "cell growth" refers to increases in cell size.
And replication
The first part of cell reproduction involves the replication of the parental cell's DNA. The second major issue is the separation of the duplicated DNA into two equally sized groups of chromosomess. The third major aspect of cell reproduction is the physical division of entire cells, usually called cytokinesis.
...
Eukaryotic cell reproduction either involves mitosis or a more complex process called meiosis. Mitosis and meiosis are sometimes called the two "nuclear division" processes.

Chromosomes duplicate in the S stage of interphase.

a million) interphase has 3 steps. G1 s section and G2. in G1 and G2 a cellular basically grows in the S section dna replication happens 2) chromosomes are made out of two chromatids. chromatids,often called chromatin are made out of DNA and protiens wrapped around eachother 3) prokaryotic cells divide via an asexual technique referred to as mitosis

I belive Prophase or Synthesis, I don't pay attention in Biology!

Interphase..to be specific the S phase.

I'd say replication.
