## Step 1The question is asking about the structure of chromosomes in eukaryotic cells during the G1 phase of the cell cycle. ## Step 2During the G1 phase, each chromosome is composed of a single, long DNA molecule that is wrapped around histone proteins. This structure is known as chromatin. ## Step 3The other options provided are not accurate descriptions of the structure of chromosomes in eukaryotic cells during the G1 phase. ## Step 4Option b suggests that there are 2 DNA molecules, which is not the case during the G1 phase. ## Step 5Option c suggests a circular DNA molecule, which is not the typical structure of eukaryotic chromosomes. ## Step 6Option d suggests an RNA molecule, which is not the primary component of chromosomes during the G1 phase. ## Step 7Therefore, the correct answer is option a, which states that each chromosome in eukaryotes in G1 contains DNA molecules in connection with histone proteins.
