Chromosomes are duplicated during the S phase of the cell cycle, specifically during DNA replication. This process ensures that each new cell formed during cell division receives a complete set of chromosomes.
Replication is when an organism's entire genome, its entire DNA sequence, makes a copy of itself. Why does it do this? Because when two cells divide, the new one needs its own personal set of instructions on what types of proteins need to be made, how much, etc. During the lifecycle of Eukaryotic cells this happens during the S (synthesis) phase where the genetic material copies itself, segregates the new from the old DNA, and then splits the nucleus in two producing two complete sets of DNA and two nuclei.
During the Synthesis (DNA replication) period.
Chromosomes are duplicated in the S (Synthesis) phase of Mitosis and Meiosis.

When during mitosis when do duplicated chromosomes separate?
Duplicated chromosomes separate during anaphase of mitosis. During this phase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
Which period are chromosomes duplicated in?
Chromosomes are duplicated during the S phase of the cell cycle, which occurs during interphase. This is when DNA replication takes place to ensure that each daughter cell receives a complete set of chromosomes during cell division.
Which of of this is not part of the process of binary fission?
Duplicated chromosomes attach to the plasma membrane.
What contains uncondensed chromosomes that have been duplicated?
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.
Where do duplicated chromosomes line up across the center of the cell?
Duplicated chromosomes line up across the center of the cell during metaphase of mitosis or metaphase II of meiosis. This alignment is crucial for ensuring that each daughter cell receives the correct number of chromosomes during cell division.
Are chromosomes in a duplicated or in unduplicated state when crossing over occurs?
It is in a duplicated state.
Are chromosomes in a duplicated or an unduplicated state when crossing over occurs?
It is in a duplicated state.
How does the number of chromosomes in metaphase of mitosis compare to the number of duplicated chromosomes in metaphase 2 of meiosis?
In metaphase of mitosis, the number of chromosomes is equal to the number of duplicated chromosomes. However, in metaphase 2 of meiosis, the number of chromosomes is half that of the duplicated chromosomes, since meiosis involves two rounds of cell division to produce haploid cells.
What are paired up chromosomes called?
duplicated
When are chromosomes duplicated before or after mitosis?
during
Name the phase of cell division when duplicated chromosomes first appear?
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
In what process are chromosomes duplicated?
Chromosomes are duplicated during the S phase of the cell cycle in a process called DNA replication. This ensures that each daughter cell receives a complete set of genetic material during cell division.
When are cells haploid but the chromosomes are still in the duplicated state?
Cells are haploid but with duplicated chromosomes during the early stages of meiosis. This occurs during meiosis I, after DNA replication in the S phase, resulting in homologous chromosomes (each with two sister chromatids) lined up before segregation.
What phase of the cell cycle has a single line of chromosomes?
During the G1 phase of the cell cycle, chromosomes are not yet duplicated and appear as a single line of chromosomes within the cell. This is before DNA replication occurs in the S phase and chromosomes are temporarily duplicated.
When do the chromosomes become duplicated?
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.
Phase if cell division when duplicated chromosomes first appear?
Prophase
Phase of mitosis in which the duplicated chromosomes separate from one another?
metaphase
