What organelle houses DNA in a neuron?

Explanation:
DNA is stored primarily in the nucleus of a neuron. In eukaryotic cells, the genome is organized into chromosomes inside the nucleus, which acts as the command center for gene expression and transcription. While mitochondria do contain their own small, separate circular DNA, it accounts for only a tiny portion of the cell’s genetic material and mainly encodes a few mitochondrial proteins. Ribosomes and the endoplasmic reticulum are involved in protein synthesis and trafficking, not in housing DNA. So, the nucleus is the organelle that holds the neuron's genetic material.
