... The knowledge of gene activity arose from the experiments of several investigators. Garrod reasoned the cause for inborn errors of metabolism. Beadle and Tatum, working with red bread mold, suggested the one gene— one enzyme hypothesis. Pauling and Itano refined this to the one gene—one polypeptide ...

Replisome
The replisome is a complex molecular machine that carries out replication of DNA. The replisome first unwinds double stranded DNA into two single strands. For each of the resulting single strands, a new complementary sequence of DNA is synthesized. The net result is formation of two new double stranded DNA sequences that are exact copies of the original double stranded DNA sequence.In terms of structure, the replisome is composed of two replicative polymerase complexes, one of which synthesizes the leading strand, while the other synthesizes the lagging strand. The replisome is composed of a number of proteins including helicase, RFC, PCNA, gyrase/topoisomerase, SSB/RPA, primase, DNA polymerase I, RNAse H, and ligase.
