fundamental molecular mechanisms in their most basic‚ accessible forms. Molecular biology was born in the laboratories of microbiologists studying viruses and bacteria. Microbes such as E. coli and its viruses are called model systems because of their use in studies that reveal broad biological principles. Microbiologists provided most of the evidence that genes are made of DNA‚ and they worked out most of the major steps in DNA replication‚ transcription‚ and translation.
