Nuclear DNA, or nuclear deoxyribonucleic acid (nDNA), is DNA contained within a nucleus of eukaryotic organisms. Nuclear DNA encodes for the majority of the genome in eukaryotes, with DNA located in mitochondria and plastids coding for the rest. Nuclear DNA adheres to Mendelian inheritance, with information coming from two parents, one male and one female, rather than matrilineally, as in mitochondrial DNA.
