Prophase 1 and prophase 2 difference

Webb4 feb. 2024 · Phase 1: Prophase Prophase is the first step of mitosis. This is when the genetic fibers within the cell’s nucleus, known as chromatin, begin to condense and become tightly compacted together. During interphase, the parent cell’s chromosomes are replicated, but they aren’t yet visible. Webb24 nov. 2024 · Prophase 1 is the initial phase of meiosis 1 and prophase 2 is the initial phase of meiosis 2.
