A
In lysosomes during cellular digestion
B
On ribosomes in the cytoplasm during protein synthesis
C
In the Golgi apparatus during secretion
D
In the nucleus during S phase of the cell cycle
Verified step by step guidance1
Understand that DNA replication is the process by which a cell makes an exact copy of its DNA, which is essential before cell division.
Recall that in eukaryotic cells, DNA is contained within the nucleus, which acts as the control center of the cell.
Recognize that DNA replication occurs during the S phase (Synthesis phase) of the cell cycle, which is the part of interphase where DNA synthesis happens.
Eliminate other organelles as sites of DNA replication: lysosomes are involved in digestion, ribosomes in protein synthesis, and the Golgi apparatus in secretion.
Conclude that DNA replication primarily takes place in the nucleus during the S phase of the cell cycle.
