The phase in meiosis where synapsis occurs

Webb11 apr. 2024 · Mitosis and meiosis are two types of cell division that occur in eukaryotic organisms. Both processes involve the replication of DNA, but the way in which this occurs differs in several key ways. In this essay, we will compare and contrast the process of DNA replication in mitosis and meiosis, highlighting the differences and similarities WebbSynapsis is the pairing of two chromosomes that occurs during meiosis.
