The Flow of Genetic Information — DNA Replication, Transcription, RNA Processing, and Translation Explained | Chapter 5 of Karp’s Cell and Molecular Biology Chapter 5 of Karp’s Cell and Molecular Biology: Concepts and Experiments examines one of the most foundational themes in modern biology: how cells store, replicate, and express genetic information. This chapter builds a detailed picture of the molecular mechanisms behind the central dogma—DNA → RNA → Protein—while integrating key experiments and enzymatic processes that make genetic expression possible. This expanded post enriches the concepts covered in the YouTube summary and provides a structured, high-level learning resource for students studying cellular and molecular biology. Be sure to watch the full chapter video above for a guided walkthrough of each process.
