What is genomic DNA?

Genomic DNA refers to the complete set of DNA that contains all the genetic information necessary for the development, functioning, and reproduction of an organism. It includes both the genes that encode proteins as well as non-coding regions that play roles in the regulation of gene expression and other functions.

The term "normal DNA" in this context signifies that genomic DNA represents the typical, unaltered genetic material found in an organism's cells, comprising all of its chromosomes. This is distinct from modified forms or DNA containing intentional manipulations, such as mutations or alterations resulting from biotechnological processes.

Genomic DNA serves as a comprehensive blueprint for an organism's hereditary traits, establishing the foundation for traits passed down through generations. Its integrity is crucial for the normal functioning and health of an organism, underscoring its role as 'normal' or 'native' DNA in the biological context.
