Want this question answered?
the S phase. this is in interphase between G1 and G2 of interphase
In Mitosis, the chromosomes duplicate themselves. In Meiosis 1, they duplicate, however they do not duplicate in meiosis 2.
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.
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.
Metaphase
the S phase. this is in interphase between G1 and G2 of interphase
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.
In Mitosis, the chromosomes duplicate themselves. In Meiosis 1, they duplicate, however they do not duplicate in meiosis 2.
Interphase, when they duplicate

Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.
prophase
The number of chromosomes that are left after mitosis is 46 in the human cell. Mitosis will just duplicate the chromosomes in the new cell and not get rid of the old ones.
Late interphase in Meiosis 1 This is the first question i ever answer correctly by the way. I can tell your sexy.
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
