Expanding DNA's alphabet lets cells produce novel proteins

Scientists are expanding the genetic code of life, using man-made DNA to create a semi-synthetic strain of bacteria—and new research shows those altered microbes actually worked to produce proteins unlike those found in ...

New evidence emerges on the origins of life

In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research is revealing ...

Genetic code used to engineer a living protein

Yale University researchers have successfully re-engineered the protein-making machinery in bacteria, a technical tour de force that promises to revolutionize the study and treatment of a variety of diseases.

Packaging process for genes discovered

Scientists at Penn State University have achieved a major milestone in the attempt to assemble, in a test tube, entire chromosomes from their component parts. The achievement reveals the process a cell uses to package the ...

DNA repair protein caught in act of molecular theft

Scientists have observed, for the first time, an intermediate stage in the chemical process that repairs DNA methylation damage and regulates many important biological functions that impact health conditions such as obesity, ...
