Understand that mitosis is the process of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell.
Recall that mitosis consists of several phases: prophase, metaphase, anaphase, and telophase.
Recognize that the question is asking about the transition from one chromatid to two sister chromatids, which is related to DNA replication.
Identify that DNA replication occurs during the S phase of Interphase, not during mitosis itself. This is when each chromosome is duplicated to form two sister chromatids.
Conclude that the transition from one chromatid to two sister chromatids occurs during the S phase of Interphase, before mitosis begins.
