Introduction: The Central Dogma of Molecular Biology Gene expression describes how the genetic code in DNA is ultimately used to build proteins. The central dogma—DNA → RNA → Protein—summarizes the flow of genetic information in all living organisms, linking genotype to phenotype. Transcription: DNA to mRNA Transcription: RNA polymerase reads a DNA template, synthesizing messenger RNA (mRNA). mRNA Processing in Eukaryotes: Addition of a 5′ cap, poly-A tail, and...
