The correct option is D In both, G1 and G2 phases
Interphase is the longest phase in a typical cell cycle. The interphase is comprised of first growth phase or G1 phase, synthesis phase or S phase and second growth phase or G2 phase. In G1 phase, there is synthesis of RNA, enzymes, proteins, amino acids for histone formation, formation of nucleotides and ATP. During G2 phase, there is again intense synthesis of proteins and RNA. Specifically, protein tubulin is formed during G2 phase.
