During which phase of the eukaryotic cell cycle does semi-conservative replication of genomic nuclear DNA take place?
Answer and explanation
Correct answer: C. S phase (Synthesis)
The interphase of the eukaryotic cell cycle is subdivided into G1 (gap 1, cell growth and organelle duplication), S phase (synthesis, where nuclear genomic DNA is replicated and centrosomes duplicate), and G2 (gap 2, protein synthesis and mitotic preparation), followed by M phase (mitosis and cytokinesis).
