In the cell cycle, sister chromatids first make up one chromosome in the prophase stage of mitosis and meiosis.

What is the cell cycle?

Cell cycle is the life cycle of eukaryotic cells from a quiescent beginning, growth, duplication of DNA followed by mitosis and division.

The cell cycle is made up of mitotic cell division i.e. division of cell's nucleus, which in turn is made up of stages as follows:

  • Prophase: The first stage of mitosis, during which chromatin condenses to form the chromosomes.

  • Metaphase: The stage of mitosis and meiosis, that follows prophase and comes before anaphase, during which condensed chromosomes become aligned before being separated.

  • Anaphase: The stage where sister chromatids of homologous chromosomes are separated.

Therefore, in the cell cycle, sister chromatids first make up one chromosome in the prophase stage of mitosis and meiosis.
