Answer:
G1-preparation for DNA replication
G2-preparation for mitosis
Explanation:
Cell cycle is a process that can be divided into two major phases: interphase and mitotic phase (division). Interphase is than subdivided into G1, S and G2 phases while mitotic phases consists of prophase, metaphase, anaphase and telophase.
Phases in interphase:
- G1 or Gap 1 is characterized by cell growth (cell becomes much larger), synthesis of molecules and organelles copying.
- S phase is characterized by DNA replication
- G2 phase or Gap 2 phase is phase in which cell makes more proteins and organelles and prepares for mitosis
