DNA Transcription (Slide 20) The ?Central Dogma? - Crick 1958 DNA - RNA - Protein Proposed that this process could not go backwards The part of DNA that encodes for a protein (or RNA) is called a gene GENE: Functional unit of DNA that codes for one or more polypeptide chains or an RNA molecule Genome is not just genes, there are intervening sequences that don?t code for a protein Proteins are generated through transcription and translation How much protein is present can be regulated by the amount of transcription and/or translation Beta-catenine- high abundance in brain (A) but low abundance in muscle (B) DN A is transcribed by RNA polymerase One RNA polymerase in bacteria that does all the transcription CORE ENZYME: 2?, 1?, 1??

Chapter 17 From Gene to Protein Lecture Outline Overview: The Flow of Genetic Information The information content of DNA is in the form of specific sequences of nucleotides along the DNA strands. The DNA inherited by an organism leads to specific traits by dictating the synthesis of proteins. Gene expression, the process by which DNA directs protein synthesis, includes two stages called transcription and translation. Proteins are the links between genotype and phenotype. For example, Mendel?s dwarf pea plants lack a functioning copy of the gene that specifies the synthesis of a key protein, gibberellin. Gibberellins stimulate the normal elongation of stems. Concept 17.1 Genes specify proteins via transcription and translation
