For decades, scientists working with genetic material have labored with a few basic rules in mind. To start, DNA is transcribed into messenger RNA (mRNA), and mRNA is translated into proteins, which ...

Natural organisms use a four-letter genetic alphabet that makes available 64 triplet codons, of which 61 are sense codons used to encode proteins with the 20 canonical amino acids. We have shown that ...

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 ...

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 ...

Start-gain mutations can introduce novel start codons and generate novel coding sequences that may affect the function of genes. In this study, we systematically investigated the novel start codons ...

A team at UT Southwestern Medical Center has identified a structural trick that lets viruses translate their genetic code inside human cells, even when that code is riddled with “bad” codons the host ...

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 ...

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 ...

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 ...
