Before prophase starts, genetic material, the DNA, is in the form of thread like structure called chromatin. As the cell division starts, it condenses to form chromosomes. So, chromosomes are further supercoiled form of chromatin and their formation demarcates the first stage that is ...
WebbMeiosis I. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase, which is also called the first gap phase, is the first phase of the interphase and is focused on cell growth. The S phase is the second phase of interphase, during which the DNA of ...
