The code of life is simple. Four genetic letters arranged in triplets—called codons—encode amino acids. These are the building blocks of proteins, the machinery that powers life. But the genetic code ...

We’ve heard of GMOs, but this is ridiculous. Scientists at the Medical Research Council’s Laboratory of Molecular Biology say they’ve engineered a bacteria whose genetic code is more efficient than ...

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 ...

In a giant feat of genetic engineering, scientists have created bacteria that make proteins in a radically different way than all natural species do. By Carl Zimmer At the heart of all life is a code.

We have gone further than ever before in creating life that is unlike anything that has evolved naturally. The genome of an Escherichia coli bacterium has been redesigned on a computer to use just 57 ...

Peking University, June 27, 2025: To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University ...

To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University led by Chen Peng from College of ...

It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to ...
