Witryna13 kwi 2024 · Abstract. Reproduction involves a wide range of biological processes, including organ formation and development, neuroendocrine regulation, hormone production, and meiosis and mitosis.

In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. greece cut minimum wage

WitrynaThe cell cycle is made up of two main stages: interphase and mitosis. During interphase, cells are duplicating their material and synthesising proteins to prepare to divide. Interphase encompasses 3 phases: G1, S and G2. During S phase, DNA is replicated. Mitosis encompasses prophase, prometaphase, metaphase, anaphase telophase.
