Biology 198 Module 4 Exam with Complete Solutions What is the Central Dogma of molecular biology? The central dogma of molecular biology explains that DNA encodes RNA through a process called transcription and RNA encodes protein through a process called translation. Describe how the information in DNA is used to produce specific proteins and can ultimately determine the characteristics of an individual organism. because of your DNA the certain RNA strand is coded from genes resulti...
