Sister chromatids are produced during the S phase of the cell cycle. Here's a step-by-step explanation:

1. The cell cycle is the process by which cells grow and divide. It consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).

2. During the G1 phase, the cell grows and prepares for DNA replication.

3. The S phase is when DNA replication occurs. The DNA in the cell's nucleus is copied. This results in two identical copies of each chromosome. Each copy is called a sister chromatid.

4. The sister chromatids remain attached to each other at a region called the centromere.

5. During the G2 phase, the cell continues to grow and prepares for cell division.

6. Finally, during the M phase (mitosis), the sister chromatids are separated and distributed to the two daughter cells.

So, sister chromatids are produced during the S phase of the cell cycle.
