Codes are big in today’s world: QR codes, barcodes, computer codes, cell phone codes, and more. Specific information is needed to identify, diagnose, and inform. DNA is the code for life: microbes, plants, parasites, animals, and man. DNA Day is April 25 because it was this day in history (April 25, 1953) when James Watson and Francis Crick described DNA as the double helix and the code for life. Although we consider DNA the genetic blueprint for life, it has only been known for 80 years. On February 1, 1944, Oswald Avery, Colin MacLeod, and Maclyn McCarty wrote a revolutionary paper about DNA as the transforming principle in Streptococcus pneumoniae, changing from harmless to pathogenic. Their fundamental discovery that DNA is the genetic material would eventually lead Watson and Crick to publish their landmark paper on the structure of DNA. This transformational discovery would eventually lead to biotechnology, an awesome skill. Credit should go to operational science discoveries by man, but greater glory to God who created DNA.

Watson and Crick acknowledged that without Avery’s lab and the Rosalind Franklin lab, they would not (80 years ago) have studied DNA (Watson 1968, 2012). Today, we use DNA to diagnose disease, discern ancestry, understand the genesis of germs, and use in biotechnology products. DNA codes are very informative. They also provide evidence of God’s wisdom and craft. DNA is, in a way, the signature of God. It is simple in code (just four letters), complex in expression (genome), beautiful in embroidery form (histones), and majestic in expression (epigenetics). The information is used in microbes and man alike, so we can also better understand the genesis of germs. Mutations since the curse (Genesis 3) cause a loss of the original code and information, and DNA helps us understand the origin of many pathogens and parasites, but we can also use DNA which uses PCR codes to identify pathogens and parasites for the diagnosis of infectious diseases.
