Want this question answered?
Chromosomes replicate in the first stage of mitosis or meiosis-interphase
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
the S phase. this is in interphase between G1 and G2 of interphase
DNA is replicated during interphase, and chromosomes form or condense during the prophase. So the genes and chromosomes are duplicated at the beginning of mitosis, during the interphase, although you can't see them as chromosomes until the prophase, before the cell splits.
Yes - interphase includes a synthesis stage (often called the 'S phase'), which comes after G1 and before G2. This is when the chromosomes are replicated.

Chromosomes duplicate themselves during interphase of a cell's life cycle.

Interphase, when they duplicate
DNA is replicated during interphase, and chromosomes form or condense during the prophase. So the genes and chromosomes are duplicated at the beginning of mitosis, during the interphase, although you can't see them as chromosomes until the prophase, before the cell splits.
Yes - interphase includes a synthesis stage (often called the 'S phase'), which comes after G1 and before G2. This is when the chromosomes are replicated.
In interphase, the DNA has just replicated and exists as loosely coiled chromatins. They have not yet condensed enough to be the form of a chromosome. In the next stage, prophase, the DNA will shorten and condense into the easily recognizable chromosome structure.
Interphase and Telophase
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is Interphase. Interphase is the first stage of the cell cycle.
i think its telophase
