How does DNA determine an organism’s characteristics? A process called translation decodes RNA created during transcription, and uses it to create proteins that perform specific cellular functions.

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 ...

The genomes of species from bacteria to Drosophila show unique biases for particular synonymous codons—varying triplet base pairs that code for the same amino acids—but it has been unclear if such ...

The genetic building blocks of life—formed from the four nucleotides adenine (A), cytosine (C), guanine (G), and thymine (T)—are read in groups of three known as codons. While some codons (known as ...

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 ...

Proteins that were present during the origin of life may have consisted of only seven primordial amino acids, a study suggests. The 20 amino acids commonly found in proteins are encoded by a total of ...

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 ...

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 ...

DNA is admired for its perfection as a programmable information molecule: it uses repeating polymerization chemistry to link four nucleotide building blocks (adenine, cytosine, guanine, and thymine) ...
