A newly identified cellular system monitors subtle variations in genetic coding, hinting at a hidden level of control over how genes are expressed.

Proteins, one of the smallest building blocks of life on Earth, hold promise for answering some of biology's biggest questions. Consisting of amino acids strung together into peptide chains, these ...

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...

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 ...

Complementary biochemical and structural findings reveal molecular principles underlying substrate selectivity by a model hyaluronan synthase.

A protein tied to ALS and dementia may have a much bigger role in disease than scientists realized. Researchers found that ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or ...

Researchers have made DNA storage rewritable, overcoming one of its biggest limitations. The breakthrough could turn DNA into a practical alternative to today’s energy-hungry data centers. The post ...
