Why Is AUG the Start Codon?: Theoretical Minimal RNA Rings

WebMar 31, 2024 · The start codon, also known as the initiation codon or AUG codon, is a three-nucleotide sequence of mRNA that signals the ribosome to begin protein synthesis. It is always the first codon in an mRNA sequence and is recognized by the ribosome as the initiation site for translation. WebThe rational design of theoretical minimal RNA rings predetermines AUG as the universal start codon. This design maximizes coded amino acid diversity over minimal sequence length, defining in silico theoretical minimal RNA rings, candidate ancestral genes. RNA rings code for 21 amino acids and a sto …
