Unformatted text preview: Key Concepts Topic 14: DNA T ranscription and T ranslation 1.) What did Beadle and Tatum figure out? In what was has their theory that one gene = one protein been revised? 2.) What are the 3 ways in which RNA and DNA differ? 3.) What does the Central Dogma say, and how do retroviruses differ from this? 4.) What is transcription, and what are the three things it requires? 5.) Why do the nucleotides participate in transcription as t riphosphates? And what are they usually? 6.) What does the promoter do in transcription? 7.) Compare the function of RNA polymerase in transcription to that of DNA polymerase in DNA replication: how are they different and how are they similar? 8.) What is a codon, and what codon begins each mRNA transcript? 9.) In what ways is the genetic code 1) Universal 2) redundant and 3) unambiguous? 10.) How do aminoacyl-tRNA synthetases assure the accuracy of translation?...
