Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing ...
The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...
Christine Dunham is a leading expert on the ribosome—an elaborate macro-molecular machine that operates like a factory within a cell to manufacture proteins. "The ribosome is really the most ...
The DNA of nearly all life on Earth contains many redundancies, and scientists have long wondered whether these redundancies served a purpose or if they were just leftovers from evolutionary processes ...
How did horses become some of the greatest athletes in the animal kingdom? Researchers at Johns Hopkins Medicine may have found the answer, pinpointing a genetic mutation and evolutionary process that ...
Most organisms on Earth have the same basic genetic code, but it comes with some flaws. Scientists sought to work out those errors by creating their own artificial genome, which replaced E. coli’s ...
A recent study by Fred Hutch biochemist Christopher Lapointe, PhD, and his colleagues, uses innovative lab techniques to ...
An illustration of E. coli. Scientists have been racing to shrink the genetic code of this bacterium. Kateryna Kon / Science Photo Library via Getty Images The DNA of nearly all life on Earth is made ...
RNA therapeutics target translation rather than DNA, aiming to correct shared protein production errors. By enabling cells to read through premature stop codons, engineered tRNAs could restore ...
