Chapter 9 Expressing Genetic Information Learning Targets Read the Focus Ons and Biological Challenges use the Chapter Highlights as well 9.1 Genetic Material I can describe: Nucleic Acids-composition of each type Types of RNA and functions Transcription and Translation Genetic Code Proteins and Amino Acids Enzymes Ribosomes Codons and Antocodons Use of the amino acid chart Proteins potential for variation 9.2 Importance of Proteins I can describe The various functions of proteins What does the structure determine. 9.3 RNA Synthesis I can describe RNA Polymerase What happens during transcription Where transcription takes place How do the RNA nucleotides pair with DNA The three stages of transcription 9.4 RNA Processing I can describe Eukaryotes vs Prokaryotes Primary vs Mature RNA Cap,tail of RNA Introns, exons, splicing 9.5 Translation I can describe Where does translation take place? What are the 3 stages and what happens in each? Charging tRNA P,A, E sites Energy needed and what stages? What happens to the parts of translations after termination? 9.6 Transport and Modification of Proteins I can describe What needs to happen to proteins to be functional? What happens after translation? Signal sequences 9.7 Translation Errors I can describe What causes most translation errors Reading frame Frame shift What can happen? 9.8 Viruses I can describe What are viruses Viral replication lytic/lysogenic Retrovirus Reverse transcription Possible Short answer C9 Describe the Functions of Proteins Describe transcription Describe RNA processing Describe translation Describe Mutations and what may cause them, give an example. Describe the two types of viral infections
