Answer:Neuronal cells in G2 phase demonstrate tetraploid (4N) DNA content or, more precisely, possess a nucleus with 46 replicated chromosomes.
Explanation:In the G1 phase, there are 12 chromosomes. In the S-phase of the cell cycle, the amount of DNA gets doubled. There is doubling of the chromatids but the chromosomes number remains same. The number of chromosomes in the G2 phase will be same as 12 chromosomes and the number of chromatids will be 24.
