The G1 phase is part of interphase within the cell cycle during which cellular content excluding chromosomes gets duplicated.
This is the part of the cell cycle where DNA replication occurs, similar to reading and understanding your recipe in our analogy.
This is a period in the cell cycle in which cells exist in a quiescent state, like deciding not to cook after all.
This phase involves further growth and preparation for mitosis - akin to prepping your cooking utensils and preheating your oven.
