1 Chapter 7: The Blueprint of Life, from DNA to Protein Important Point: Molecular Genetics Overview ± Genome = cell’s complete set of genetic information. ± In practice genome does not include plasmids. ± Genome, for most bacteria, is synonymous with chromosome (since chromosome is singular for most bacteria). ± The genome of all cells consists solely of DNA. ± For some viruses the genome is RNA, however. ± Genes are the most noteworthy aspect of genomes. ± Traditionally, most genes encode proteins (though in reality a great number of genes instead encode individual polypeptides or non-mRNA RNAs). ± Central Dogma of Molecular Genetics: ± Replication = DNA to DNA information transfer. ± Transcription = DNA to RNA information transfer. ± Translation = RNA to protein information transfer. ± Reverse transcription = DNA to RNA information transfer. Central Dogma Transcription, catalyzed by RNA Polymerase, is the first step of Gene Expression. Translation is
