Question

the synthesis (s) phase is characterized by
a. dna replication.
b. the division of cytoplasm.
c. replication of mitochondria and other organelles.
d. cell division.

Explanation:

The S (synthesis) phase is part of the eukaryotic cell cycle's interphase. Its core function is to duplicate the cell's genetic material to prepare for cell division. Cytoplasm division (cytokinesis) occurs after mitosis, organelle replication happens mainly in G2 phase, and cell division encompasses mitosis and cytokinesis, not the S phase.

Answer:

A. DNA replication.
