Genetics and Morse code. Conceptual image of the double helix molecule of DNA (deoxyribonucleic acid), overlaid with dots and dashes representing Morse code. Both are ways of encoding and transmitting information. DNA contains the genetic code that varies between different organisms, producing different body structures and chemistry. It is the sequence of nucleotide bases in DNA that forms the genetic code. Morse code (named for Samuel Morse, an inventor of the telegraph) was developed from the 1830s, with the International Morse code adopted in 1865.
