"Our opponents talk about marriage like it's been the same for 6,000 years." Count on the religious right's taking the issue to the G.O.P. Convention in San Diego--and trying to force into the platform a plank banning same...
After characterizing the lambda repressor, Ptashne began applying the principles of gene regulation in lambda phage virus to higher organisms...
...made a few observations that enabled us to argue that the principles of gene regulation in higher organisms can be understood with certain modifications of what we know in lambda," Ptashne says. "Those principles of gene regulation in higher organisms were then explained in the second edition of 'A Genetic Switch...
...focus is different from that of many labs working on gene regulation." Ptashne says. "It's not so much discovering new examples of regulators but rather understanding what are the common chemical principles that regulate genes. The message from lambda is that you can't study the patterns of gene expression without studying the underlying mechanism...
Ptashne says that Nusslem Volhard's work on the development of front fly embryos shows that many of the complicated patterns of gene regulation during development can be understood in terms of the Lambda mechanism...
