Reading mRNA Like Source Code

Description

A cropped document screenshot shows the WHO emblem and the heading "WHO International Nonproprietary Names Programme," with the date "9/2020" at the top right. Below it is the multilingual header "Sequence / Séquence / Secuencia" followed by dense biological sequence text made of letters such as G, A, C, and the modified-base symbol Ψ, with right-side line counts from "50" through "500." The sibling context points to Bert Hubert's article "Reverse Engineering the source code of the BioNTech/Pfizer SARS-CoV-2 Vaccine," where this WHO sequence is explained as the first 500 characters of the BNT162b2 mRNA. The technical relevance is the code-like treatment of molecular information: encoded instructions, modified symbols, translation machinery, and optimization choices that map surprisingly well to software metaphors.
