Biological complexity — DNA as digitally encoded information pointing to design

Life contains digitally encoded information. DNA consists of nucleotide base pairs (A, C, T, G) arranged along a sugar-phosphate backbone. The sequential arrangement of these bases determines the sequence of amino acids in proteins. DNA is transcribed into mRNA, which is translated at ribosomes into proteins. The codon system (64 triplets of nucleotides specifying 20 amino acids) functions like words in a language — each codon is a three-letter word. This information-based architecture of life is precisely what we'd expect if an intelligence designed it.
