The dictionary of life has a new update. A DNA sequence that signals cells in almost all other organisms to stop synthesising proteins instead encodes a rare amino acid in some archaea, according to a ...

One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of ...

Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque ...

For decades, amino acids have been added to medical formulations like insulin as stabilizers: these small molecules keep proteins (i.e. larger particles) from interacting in undesirable ways. And for ...

University of Queensland researchers have developed an affordable, open-source DNA measurement tool that can be built using a home 3D printer. The Do-It-Yourself Nucleic Acid Fluorometer—DIYNAFLUOR—is ...

Our Amino Acid Composition Calculator provides a fundamental analysis of your protein sequence. By simply inputting a sequence, this web-based tool instantly calculates the absolute number and ...

Our DNA to Amino Acid Converter helps you translate genetic sequences into protein structures quickly and easily. You can use it with standard or specialised genetic codes, and it accepts DNA or RNA ...

These days, the supplement aisle is growing by the minute, and that’s especially the case when it comes to sports and athletic performance supps. There’s protein powder, creatine, amino acids—and you ...

Protein is everyone's favorite macronutrient right now. But focusing on the grams you get in a day isn't enough, dietitians say. You should also make sure to vary your protein sources so that you get ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...
