Understanding DNA and Its Significance in Scientific Field
DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions for the development and functioning of living organisms. It is often referred to as the “building blocks of life.” DNA is found in every cell of an organism and plays a fundamental role in biological studies and research.
Defining DNA
DNA is a double-stranded molecule that consists of four nucleotide bases: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up in a specific way, with A always pairing with T and G always pairing with C. The sequence of these bases along the DNA molecule determines the genetic code.
Distinction between genomic DNA and other types of DNA
Genomic DNA refers to the complete set of DNA present in an organism’s genome. It includes all the genes, as well as the non-coding regions that regulate gene expression.
