These operator sequences in DNA act in cis; ... The operon: A group of genes with expression coordinated by an operator. Comptes Rendus Biologies 328, 514–520 (1960) ———.

Here, we designed synthetic epigenetic memory systems using DNA methylation sensitive engineered zinc finger proteins to repress a memory operon comprising the CcrM methyltransferase and a reporter.

By the spring of 1971, Mertz had the DNA pieces she needed. But Berg’s lab still lacked a method for making this trivalent recombinant DNA. Once introduced into E. coli and replicated there to high ...

Mystery of operon evolution probed Date: August 30, 2012 Source: Rice University Summary: New research suggests a possible explanation for the organization of operons, jointly controlled clusters ...

An operon is defined as a functional unit of DNA that contains a group of genes under the control of same promoter. The lac operon in E. coli contains three structural genes, ...
