Among eukaryotes, replication of DNA takes place in:
S phase
G1 phase
G2 phase
M Phase
Among eukaryotes, DNA replication primarily takes place during the S (Synthesis) phase of the cell cycle. During this phase, the cell's DNA is replicated in preparation for cell division.
So, the correct answer is (A): S phase.
The sequence of growth and division of a cell, and consists of a series of biological processes, particularly the resting phase (G0), the interphase (G1, S, G2), and cell division (i.e. mitosis and cytokinesis)
