gDNA stands for Genomic DNA, a genetics abbreviation.

The complete chromosomal DNA of an organism, extracted from cells or tissue, including both genes and non-coding regions. The term distinguishes it from cDNA, plasmid DNA or mitochondrial DNA in laboratory protocols.

Example: gDNA was extracted from buccal swabs using a silica-column kit.

Usage notes

Genomic DNA from eukaryotes contains introns, regulatory sequences and repetitive elements that cDNA lacks. Contaminating gDNA can produce false signals in RNA experiments, so samples are often treated with DNase before reverse transcription.
