DNA is found in the nucleus where it directs the transcription and translation of genes, in mitochondria where it encodes for some of the proteins needed for oxidative phosphorylation, and in chloroplasts where it encodes for some of the proteins needed for photosynthesis. DNA is not typically found in peroxisomes. Therefore, the correct choice is D: in the nucleus, mitochondria, and chloroplasts.
