During which specific phase of the eukaryotic cell cycle does the replication of nuclear deoxyribonucleic acid take place?

A. G one phase
B. S phase✓ Correct Answer
C. G two phase
D. M phase

💡 Solution & Explanation

The synthesis phase, commonly known as S phase, occurring during interphase of the cell cycle is dedicated to the precise replication of nuclear DNA and duplication of centrosomes. G one phase involves cell growth and protein synthesis preceding DNA replication, whereas G two phase involves final preparations for mitosis. M phase encompasses nuclear division through mitosis followed by cytokinesis. Cell cycle checkpoints regulate progression to prevent genetic mutations.
