All of the following are related to a G1 phase of the cell cycle except:
Correct answer: D. Energy storage for chromosomal movement.
- A. Extensive metabolic activities.
- B. Cells growing in size.
- C. Accumulation of aaDNA base units.
- D. Energy storage for chromosomal movement.
Explanation
G1 phase is characterized by the extensive metabolic activities, cell growth, synthesis of specific enzymes and accumulation of nucleotides for DNA replication while the G2 phase is characterized by the storing of energy for chromosomal movement, synthesis of mitotic specific proteins, RNA and microtubule subunits.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
