Bacteria can acquire resistance to antibiotics through random mutations in their DNA that provide them with an advantage that helps them survive. Finding genetic mutations, and discovering how they ...

Synonymous or silent mutations do not change the sequence of the protein that they encode. With some exceptions, they do not trigger any effect. Last year, however, a study by researchers from the ...

Infographic: How “Silent” Mutations Can Disrupt Protein-Making Although scientists often assume that synonymous mutations don’t cause any biological effects because they don’t alter the amino acid ...

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

Although previously thought to be neutral, research in yeast suggests that synonymous point mutations may have strongly nonneutral effects. A group of researchers from the University of Michigan (MI, ...

This is a visual readout of the varied effects of silent mutations in the bacteria, Salmonella enterica. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted ...

Occasionally, single-letter misspellings in the genetic code, known as point mutations, occur. Point mutations that alter the resulting protein sequences are called nonsynonymous mutations, while ...

Geneticists have sought to understand the impact of genetic mutations, and what drives and maintains changes in DNA. Researchers have now reconstructed the evolution of a set of genes, and the ...
