Organelles and chromosomes are copied during S phase and G2 phase of Interphase in Mitosis. More particuarlly, the S phase is where DNA replication occurs and the G2 phase synthesizes proteins and organelles needed in Mitosis.
Cell division. Each time a cell divides, it reproduces a copy of the existing chromosomes, and each copy then resides in both of the new cells.
A cell duplicates its chromosomes during the S phase. DNA replication should be precise and accurate in order to prevent genetic abnormalities.
The DNA of cells is found on the chromosomes which are located in the nucleus. During mitosis, cells divide to form exact copies of the chromosomes and therefore themselves.

During the cell cycle, chromosomes are duplicated during the interphase.
The nucleus of a cell contains uncondensed chromosomes that have been duplicated. During the interphase of the cell cycle, before cell division, the chromosomes replicate and form sister chromatids that are still uncondensed and spread throughout the nucleus.
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.
during prophase, in order to allow microtubules to attach to the duplicated chromosomes
during
the chromosomes are duplicated.

Duplicated chromosomes first become visible during prophase.
During the cell cycle, chromosomes are duplicated during the interphase.
Chromosomes are duplicated in the interphase of cell division.
Chromosomes become duplicated during meiosis. This is the process of replicating sex cells, otherwise known as gametes. This is how humans create new sex cells for reproduction.
The S phase in the interphase. Chromosomes are copied in the interphase part of the cell cycle S phase would be the answer. It is during Interphase (G1, S, G2) that they are copied. SO dependant on your answers it's either interphase or S.
Chromosomes separate during the anaphase stage of meiosis or mitosis. During this stage the chromosomes move to the opposite ends of the cell.
The nucleus of a cell contains uncondensed chromosomes that have been duplicated. During the interphase of the cell cycle, before cell division, the chromosomes replicate and form sister chromatids that are still uncondensed and spread throughout the nucleus.
It is in a duplicated state.
