Somewhere in a sample of ordinary pond water, a single-celled organism has been quietly breaking one of biology’s most fundamental rules. Condylostoma magnum, a free-living ciliate barely visible to ...

A central tenet of biology may need updating given new measurements of start codons. For decades, scientists working with genetic material have labored with a few basic rules in mind. To start, DNA is ...

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 ...

Cells working with an expanded genetic code could make more diverse medicines. A new study shows scientists are within striking distance. One of modern biologists' most ambitious goals is to learn how ...

Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or codons—specify one of many amino acids, the building blocks of proteins. Multiple ...

In April 2021, Jamie McGowan was running a routine test. A computational biologist at the Earlham Institute in Norwich, ...

Our genes are written in long strings of three-letter units composed of four different nucleotides. These units - or codons - specify one of many amino acids, the building blocks of proteins. Multiple ...

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 ...

Superimposed on the genetic sequences coding for amino acids is a second genetic code. This second genetic code, which makes use of dual-use codons, or duons, specifies how genes are controlled. The ...
