Final answer:
These stages include G1, S, G2, and mitosis. During G1, the cell grows and carries out normal functions, while S phase involves DNA synthesis and chromosome duplication. G2 phase is the preparation stage for mitosis, and in mitosis, the chromosomes are separated into the daughter cells.
Step-by-step explanation:
In order to determine the stage of the cell cycle based on the snapshot of chromosomes, one must consider the changes in gene expression. The cell cycle consists of various stages including G1, S, G2, and mitosis. During G1, the cell grows and carries out normal functions. In S phase, DNA synthesis occurs and chromosomes are duplicated. In G2 phase, the cell prepares for mitosis. Finally, during mitosis, the duplicated chromosomes are separated into two daughter cells.
