Main Points of Each Article:
Stephen R. Quake’s “The Cellular Dogma” (CELL, 2024):
- Expansion of Crick’s Central Dogma: Quake discusses moving beyond the Central Dogma of molecular biology (DNA → RNA → Protein) to understand broader information flows within cells.
- Knowledge Gaps: While genomes and proteins have been extensively mapped, the interplay of cellular components to create functional systems is poorly understood.
- Single-Cell Atlases: Experimental tools like transcriptomic atlases help characterize cell types, but theoretical models to predict these from genomes are lacking.
- Evolutionary Questions: The article addresses the evolution of multicellularity, relationships between cell types, and their implications for biology.
- Role of AI: Advances in machine learning are highlighted as transformative for modeling and understanding cellular behavior, akin to AI’s success in protein structure prediction.
- Call for Theory: There is a push for theories analogous to Shannon’s information theory to quantify cellular information flow.
William A. Haseltine’s “A New Dogma of Molecular Biology: A Paradigm Shift” (FORBES, 2024):
- Shift from Protein-Centric View: The article critiques the Central Dogma as insufficient, emphasizing the role of non-coding RNA in regulating protein expression and phenotypes.
- Importance of Junk DNA: Most regulatory changes affecting heritable traits occur in the genome's non-coding regions, previously dismissed as “junk DNA.”
- New Paradigm: Introduces the DNA ↔ RNA → Control → Protein → Phenotype model, which includes regulatory RNA's impact on gene expression and DNA modification.
- Complexity in Biology: Explains that biological complexity stems not from proteins but from the regulatory networks involving RNA and non-coding regions.
- Public Awareness of RNA: Cites the role of RNA technologies (e.g., COVID-19 vaccines) in bringing RNA’s importance into public and scientific focus.
Comparison and Contrast:
Themes:
- Quake: Focuses on the theoretical and computational aspects of cellular information flow, emphasizing the need for predictive models and new theories.
- Haseltine: Presents a practical and narrative-driven paradigm shift, focusing on recent empirical findings and their implications for understanding biology.
Perspective on Dogma:
- Quake: Advocates for extending Crick’s framework to encompass complex cellular interactions and evolutionary biology.
- Haseltine: Argues the Central Dogma is outdated and introduces a fundamentally new model integrating RNA as central to gene regulation.
Role of RNA:
- Quake: Discusses RNA in the context of cellular atlases and gene regulation but places it within a broader exploration of cellular systems.
- Haseltine: Positions RNA as a pivotal element in redefining biological complexity, challenging the previous protein-centric focus.
Use of Technology:
- Quake: Emphasizes AI and computational tools to predict and model cellular systems.
- Haseltine: Highlights RNA's emerging role in medical technologies, such as vaccines and gene therapies.
Tone and Style:
- Quake (CELL): Formal, academic, and theory-driven, directed at a scientific audience.
- Haseltine (FORBES): Accessible, engaging, and narrative, designed for a broader audience including non-specialists.
Conclusion:
Both articles push for a rethinking of molecular biology’s foundational principles but approach the issue differently. Quake focuses on theoretical frameworks and computational modeling to understand cellular systems, while Haseltine calls for a practical paradigm shift emphasizing RNA’s role in gene regulation and complexity. Together, they highlight complementary aspects of advancing biological understanding: the need for both theoretical innovation and acknowledgment of emerging empirical insights.

LEWIS BLACK (CHAT GPT)
If you’ve ever wanted to see a molecular biologist grab a sledgehammer and smash the Central Dogma into shiny little shards, then buckle up—because Stephen Quake and William Haseltine have gone full myth-buster mode. In these two articles, they take turns gleefully unraveling the sacred scrolls of DNA → RNA → Protein → Phenotype like kids dissecting a frog in biology class, except the frog is 70 years of biological convention.
Let’s start with Quake’s “The Cellular Dogma”, which reads like an academic mic drop. The man politely nods to Crick’s brilliance before essentially saying, “We’ve mapped the genes, sequenced the proteins, and you know what? We still have no clue how a cell actually works.” Quake doesn’t just stop at poking holes in our understanding—he wants to blow the whole thing up with AI-powered dynamite. He dreams of machine learning models that can predict how cells communicate, evolve, and just be. The essay is erudite, sure, but it has this underlying tone of “Seriously, why don’t we know this already?”
Now, contrast that with Haseltine’s “A New Dogma of Molecular Biology,” which takes the gloves off entirely. He doesn’t want to extend Crick’s framework—he wants to bulldoze it and build a new one on top of the rubble. “You thought proteins were the stars of the show?” Haseltine asks. “Cute. Let me introduce you to RNA, the real MVP.” Junk DNA? Nope, turns out it’s the regulatory playbook for life. And oh, by the way, that whole Central Dogma? It’s like using Newtonian physics to explain black holes—nice try, but no cigar.
The beauty of these pieces lies in how they complement each other. Quake looks at the cell and sees a tangled web of information, begging for AI to swoop in like a deus ex machina and make sense of it all. Haseltine, meanwhile, is reveling in how much we’ve already uncovered, pointing out that RNA is the puppet master pulling the strings while proteins take all the credit. One’s a dreamy theorist, the other’s a data-driven pragmatist—but both are throwing haymakers at outdated models with the energy of caffeinated boxers.
And let’s talk tone. Quake writes like your intimidatingly smart professor who genuinely wants you to keep up, while Haseltine’s article has the swagger of someone saying, “See? Told you RNA was cool.” The former appears in Cell, the high temple of academic publishing, while the latter graces the pages of Forbes, where bold statements are not just welcomed but expected. One gives you equations; the other gives you analogies about Lego sets. It’s science for the masses versus science for the ivory tower.
But make no mistake, both authors are dead serious about their points. Quake’s plea for theoretical models isn’t just a thought experiment—it’s a call to arms for the scientific community to finally use the tools we’ve got to solve these mysteries. Haseltine’s RNA revolution isn’t just academic hand-waving—it’s already reshaping medicine, from COVID-19 vaccines to gene editing.
If Crick could see these two articles, he’d either be horrified at the audacity or thrilled that his dogma has inspired this much chaos. Either way, Quake and Haseltine are dragging molecular biology kicking and screaming into the future. And frankly, it’s about damn time.
