Introduction: [|Ch10ProtSynInfoAude.doc] (vocabulary, readings...) Guided reading questions: [|Ch10ProtSynQuestions.doc] (for open notes quiz) After Quiz Questions: [|ProtSynthInClassQu.doc] (to be handed in) . [|PowerPoint] Presentation, hosted by SlideShare

This BioCoach activity will help you review [|transcription], the synthesis of RNA from DNA. You will find information about the organization of genes, the structure of RNA, the transcription process, and the differences between mRNA in prokaryotes and eukaryotes. Animations show the transcription process in a dynamic way. You can test your understanding of transcription by using the Self-Quiz at the end of the module. By continuing on to the activity on translation, you can then learn about how mRNA is translated into protein.

This BioCoach activity will help you review [|translation], the synthesis of protein from mRNA. You will find information about the structure of proteins, the genetic code, the molecular components of translation, and the process of assembling a protein chain as a ribosome moves along an mRNA molecule. Animations show the translation process in a dynamic way. You can test your understanding of translation by using the Self-Quiz at the end of the module.

This [|BioCoach activity] will help you understand how gene expression is regulated in bacteria, causing genes to be turned on and off in response to environmental signals. You will find information on how genes in bacteria are grouped together in functional groups called operons, the functions of various segments of DNA in operons, how specific molecules start and stop transcription within operons, and how certain molecules affect the rate of this transcription. Animations in the activity show these processes. You can check your understanding of the //lac// operon by using the interactive Practice exercises and the Self-Quiz at the end of the module.
