DNA Transcription and Translation Objectives Identify the structure of RNA List the 3 types of RNA Understand why transcription must occur Identify the different steps of transcription. What are we trying to do? Transcription- we are trying to make a ?messenger? to code for a protein. Translation- making the protein! Gene Segment of DNA that codes for a protein DNA codes for RNA and RNA makes protein (central dogma) One Gene ? One Enzyme The Beadle and Tatum experiment showed that one gene codes for one enzyme. One gene codes for one polypeptide. polypeptide - a chain of covalently bonded amino acids. (proteins are made of one or more polypeptide) Let?s make some observations about RNA?s structure RNA RNA stands for: Ribonucleic acid RNA is found:
