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 ...

Scientists have demonstrated RNA polymerase can read eight genetic letters. This enzyme accurately transcribes synthetic DNA, ...

There are few hard and fast rules in the study of life, but perhaps the closest we get is the central dogma of molecular biology: DNA is transcribed to RNA, which gets translated into proteins. The ...

In a shallow pond at Oxford University Parks, surrounded by dog walkers and rowing crews, a single-celled organism has been quietly defying one of biology’s most fundamental rules. A team led by ...

The genetic code is central to life. With minor variations, everything uses the same sets of three DNA bases to encode the same 20 amino acids. We have discovered no major exceptions to this, leading ...

Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to be the way it is? "We find ...

A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers stumbled upon a bizarre genetic code in a microscopic pond organism.

Got junk? Learn how a new study suggests that, when it comes to our genetic code, that may actually be a good thing. We all have one: a junk drawer that we stuff full of all our random — and often ...

I wonder if the pre-LUCA ribosome itself might have been radically different before we fixed on 20 amino acids? Obviously the protein scaffolding would be different, but also it could afford to be a ...
