DNA doesn’t “do", it instructs. In this episode of the Jack Westin MCAT Podcast, Mike and Molly walk through the central dogma, how we go from DNA → RNA → protein—and the regulation that makes different cells, well, different. Perfect for MCAT Bio/Biochem: we hit transcription, RNA processing, translation mechanics (A–P–E sites), start/stop codons, eukaryote vs. prokaryote differences, and multi-layered gene expression regulation (chromatin, transcription factors, miRNA/siRNA, ubiquitin, & more).🔑 What you’ll learnCentral dogma overview (DNA → RNA → protein)Transcription: promoter, template vs. coding strand, initiation/elongation/terminationEukaryotic RNA processing: 5′ cap, splicing (introns vs. exons, alternative splicing), poly-A tailTranslation: AUG start (Met), codons/anticodons, tRNA charging, ribosome A–P–E sites, stop codons (UAA/UAG/UGA)Eukaryotes vs. Prokaryotes: 40/60/80S vs. 30/50/70S ribosomes, coupled transcription–translation, operons (lac/trp)Regulation: heterochromatin vs. euchromatin, histone acetylation, DNA methylation, transcription factors, miRNA/siRNA silencing, post-translational mods (ubiquitin, phosphorylation)Want to learn more?
