Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

The same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code. Andrzej Wojcicki/Science Photo Library via Getty Images Nearly all life, from bacteria ...

Two-faced codon rewrites genetics? The genetics of a marine protozoan may overturn one of the long-held tenets of protein synthesis. According to conventional wisdom, the genetic code is unambiguous: ...

As wildly diverse as life on Earth is—whether it’s a jaguar hunting down a deer in the Amazon, an orchid vine spiraling around a tree in the Congo, primitive cells growing in boiling hot springs in ...

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 ...

For decades, biology has relied on one central assumption: the genetic code is precise. DNA is transcribed into RNA, RNA is ...

How did horses become some of the greatest athletes in the animal kingdom? Researchers at Johns Hopkins Medicine may have found the answer, pinpointing a genetic mutation and evolutionary process that ...

A genetic disorder is a condition that occurs as a result of a mutation to DNA. There are several different genetic disorders. Most cells within the body contain the molecule DNA. This molecule ...

Genetic testing is a minimally invasive medical test that doctors use to identify genetic mutations or variants that can lead to certain diseases or conditions. Doctors use various types of genetic ...
