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.
