Every known organism writes genetic information with four DNA letters, but laboratory chemistry is not limited to that ...
Scientists have demonstrated RNA polymerase can read eight genetic letters. This enzyme accurately transcribes synthetic DNA, which nature never evolved. Such findings expand the design space for new ...
Nevertheless, some preliminary steps have been taken. Researchers have managed to add some new amino acids to a bacterial ...
A new study reveals all five fundamental nucleobases – the molecular “letters” of life – have been detected in samples from the asteroid Ryugu. Asteroid particles offer a glimpse into the chemical ...
In my first semester of graduate school at Tufts University, I sat across from a young professor as he pitched me on joining his lab to work on genetic code expansion (GCE). Even though I'd just ...
