14 Μαρ 2017 · The main difference between prophase 1 and 2 is that genetic recombination occurs through crossing overs and the “Chiasmata” formation during prophase 1 whereas no genetic recombination is noticed at the prophase 2.
6 Ιαν 2018 · Prophase I Longest and most complex phase. 90% of the meiotic process is spent in Prophase I. Chromosomes condense. Synapsis occurs: homologous chromosomes come togather to form a Tetrad. Tetrad is two chromosomes or four chromatids (sister and non-sister chromatids).
Present the basic stages of mitosis and then highlight how this process can vary among different organisms, such as plants, animals, and fungi. Use diagrams, videos, or animations to illustrate these variations.
3 Αυγ 2023 · Prophase is the phase that follows the interphase and typically the first and longest phase in the cell cycle, for both mitosis and meiosis. It is the phase of DNA unwinding and chromatin condensation to make the chromosomes visible. What Happens in Prophase?
16 Μαΐ 2023 · Prophase 1 Meiosis It is the longest phase of meiotic division involving a series of events and is divided into the following steps: The duplicated chromosomes condense, resembling an X-shaped structure with two sister chromatids that become distinctly visible within the nucleus.
Events that occur during prophase of mitosis also occur during prophase I of meiosis. The chromosomes coil up, the nuclear membrane begins to disintegrate, and the centrosomes begin moving apart. The two chromosomes may exchange fragments by a process called crossing over.
