How many chromosomes are in the cell after S phase?

After the S phase of the cell cycle, the number of chromosomes remains the same, but each chromosome consists of two sister chromatids. For example, in humans, there are 46 chromosomes, and after S phase, there are still 46 chromosomes, but they are duplicated, resulting in 92 chromatids. This duplication prepares the cell for mitosis, where the sister chromatids will be separated.
