Chapter 17
17.1 – genes specify proteins via transcription and translation
17.2 – transcription is the DNA-directed synthesis of RNA
17.3 – eukaryotic cells modify RNA after transcription
17.4 – translation is the RNA-directed synthesis of a polypeptide
17.5 – mutations of one or a few nucleotides can affect protein structure and function
17.6 – while gene expression differs among the domains of life, the concept of a gene is universal

Chapter 18
18.1 – bacteria often respond to environmental change by regulating transcription
18.2 – eukaryotic gene expression is regulated at many stages
18.3 – noncoding RNAs play multiple roles in controlling gene expression
18.4 – a program of differential gene expression leads to the different cell types in a multicellular organism
