A genetic mutation and evolutionary trick fuels horses' exceptional athleticism, findings that may advance scientific ...

Horses have a rare genetic adaptation that helps improve athleticism. This evolutionary mechanism could improve human ...

It basically put a stop sign, called a stop codon, toward the beginning of the KEAP1 gene. Stop codons generally signal where a gene ends, so having one at the start would "break" the gene.

In preparing for their study, the researchers came across a premature stop codon in equine versions of the gene compared to other species. Located unusually early in the protein sequence ...

They also highlight how the recoding of a de novo stop codon – a strategy thought restricted to viruses – can facilitate adaptation in vertebrates. Long prized for their speed and endurance ...

During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop signal (stop ...

Note also that the codon for the amino acid methionine (AUG) acts as the start signal for protein synthesis in an mRNA. Moreover, the genetic code also includes stop codons, which do not code for ...
