During the cell cycle, chromosomes are duplicated during the interphase.
Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
two molecules are formed, each with the original "upright"
DNA duplication occurs during the interphase, specifically the S phase. After replication, the cell then enters the first active phase of mitosis.
Before they are pulled apart they are called sister chromatids. Once they are pulled apart they are called chromosomes.
Chromosomes can be seen during cell divison, Reference Before a cell gets ready to divide by mitosis, each chromosome is duplicated (during S phase of the cell cycle
DNA replication occurs during the S phase of interphase, which is the phase that precedes mitosis. In this phase, the DNA molecules in the cell's nucleus are duplicated, resulting in two identical copies of each chromosome.
No, in Metaphase the chromosomes align in the center of the cell in association with the spindle fibers, and PREPARE to duplicate during the next phase of Mitosis, which is Anaphhase. The chromosomes are developing to duplicate throughout all phases of mitosis up until Anaphase when the chromosomes split into two and cytokinesis begins to take place so that two new cells will be formed.
The S phase in the interphase. Chromosomes are copied in the interphase part of the cell cycleS 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.
