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 ...

Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

Protein barcodes are short, information- rich stretches of amino acids encoded by DNA sequences that can be added to the DNA sequences coding for proteins. Then, when protein barcode DNA and protein ...

There are hundreds of diseases affecting humans that result from errors in cellular production of its proteins. A team led by researchers at the University of Massachusetts, Amherst, report they ...

From viruses to humans, life makes microproteins that have evaded discovery until now. By Carl Zimmer You could be forgiven for assuming that scientists know how many kinds of proteins exist. After ...
