Genomic deoxyribonucleic acid is chromosomal DNA, in contrast to extrachromosomal DNAs like plasmids. It is often abbreviated as gDNA.[1]

The genome of an organism (encoded by the genomic DNA) is the biological information of heredity which is passed from one generation of organism to the next. That genome is transcribed to produce RNAs, which are necessary for the function of the organism. Some RNA is processed by splicing to remove introns, leaving the exons in the mature messenger RNA (mRNA). The mature mRNA may then be translated by the ribosome into protein.
