Recall the stages of meiosis I: Prophase I, Metaphase I, Anaphase I, and Telophase I, along with Interphase which occurs before meiosis begins.
Understand that spindle fibers are structures made of microtubules that help separate chromosomes during cell division.
Identify that spindle fibers begin to form and attach to chromosomes during the early stages of meiosis, specifically when chromosomes condense and become visible.
Recognize that during Prophase I, homologous chromosomes pair up, condense, and spindle fibers start to form and attach to the chromosomes' kinetochores.
Conclude that the stage when spindle fibers first form and begin attaching to chromosomes is Prophase I.
