During interphase, RNA and proteins are synthesized in:
Options
- AS phase
- BG 1 phase
- CG 2 phase
- DBoth G 1 and G 2 phases
Correct answer
D. Both G 1 and G 2 phases
Step-by-step solution
G 1 phase is also known as post-mitotic or pre-synthetic phase or first growth phase. It involves synthesis of proteins (enzymes) and energy molecules required for DNA replication.G 2 phase is second growth phase and also called pre mitotic gap or growth phase. It involves the synthesis of the tubulin, the spindle protein and RNA.
