Answer:
a. a cell during the G1 phase of interphase
Explanation:
The cell cycle is composed by a series of events that occur within the cell in order to duplicate its DNA for the subsequent production of two daughter cells from a sinlge one.
The cell cycle consists of three states: Interphase (composed of phases G1, S and G2 occurring in this order), Cell division (mitosis) and Resting.
During interphase, specifically in S phase, the cell replicates the genetic material of its chromosomes to prepare itself for cell division. This means that in the previous phase-G1-, the cell has not yet replicated its DNA
During mitosis (prophase to telophase), the chromosomes are duplicated in the cell. The genetic material is distributed in two cells after cytokinesis.
