During which phase are centrioles replicated and protein synthesis continues?

Explanation:
Centriole duplication begins during the S phase, when DNA is being replicated. Protein synthesis is active throughout interphase, continuing through S and into G2 to supply the proteins needed for growth and for the upcoming division. Because centriole duplication starts in S phase and protein synthesis is ongoing then, this phase is when both processes occur. (Mitosis involves chromosome separation and spindle function, but centriole duplication is not initiated there; G1 focuses on growth and G2 focuses on final prep before division, after centriole duplication has begun in S.)
