Most of the proteins required for division are synthesized during this phase. The duration of the G1 phase can vary from cell to cell or also on the availability of nutrients.

WebbProphase During prophase, the chromosomes, which had been thin and threadlike in interphase, begin to condense, or thicken. The nuclear membrane surrounding the cell … WebbProphase I Explanation: When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Webb24 nov. 2024 · The cell cycle consists of the gap 1 phase (G 1 phase), synthesis phase (S phase), and gap 2 phase (G 2 phase), and lastly, the mitotic phase. Interphase is essentially when the cell is not actively dividing, so all phases of the cell cycle except for the mitotic phase and cytokinesis. WebbThe interphase is divided into three phases; G 1 phase, the cell grows in size and makes necessary proteins in this phase. S phase, the cell undergoes DNA replication. G 2 phase, the cell makes proteins that are needed for meiosis. After the G 2 phase is complete, the cells enter Prophase I.
