Definition
Meaning and Definition
The complete set of DNA contained within the chromosomes of an organism, carrying the genetic instructions for its development and functioning.
In laboratory and research contexts, it refers to DNA isolated directly from cells or tissues, as opposed to complementary DNA (cDNA) or plasmid DNA. It represents the organism's full genetic blueprint, including both coding and non-coding regions.

FAQ
Frequently Asked Questions
No. A gene is a specific functional unit within genomic DNA. Genomic DNA contains all of an organism's genes plus non-coding regions.
Genomic DNA is the natural DNA from chromosomes, including introns and regulatory sequences. cDNA (complementary DNA) is synthesized from messenger RNA and contains only the exons of expressed genes.
It is atypical and often considered incorrect in standard technical writing. 'Genomic DNA' is treated as a mass noun (like 'information'). You would say 'samples of genomic DNA' or 'genomic DNA samples'.
It is fundamental in genetics, molecular biology, genomics, forensic science, genetic medicine, and biotechnology.
The complete set of DNA contained within the chromosomes of an organism, carrying the genetic instructions for its development and functioning.
Genomic dna is usually technical/scientific in register.
Genomic dna: in British English it is pronounced /dʒɪˌnəʊ.mɪk ˌdiː.enˈeɪ/, and in American English it is pronounced /dʒɪˌnoʊ.mɪk ˌdiː.enˈeɪ/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of the GENOME (the full set of instructions) made of DNA. Genomic DNA is the physical book, not just the chapter summaries (cDNA).
Conceptual Metaphor
The master blueprint or the complete encyclopedia of an organism's genetic information.
