In other words, mutations occur randomly with respect to whether their effects are useful. Thus, beneficial DNA changes do not happen more often simply because an organism could benefit from them.

Only around two percent of the human genome codes for proteins, and while those proteins carry out many important functions ...

Scientists discovered that DNA mutations influence aging by altering epigenetic changes and biological clocks.

A new study draws a line between random genetic mutations and predictable epigenetic changes used to measure biological aging ...

In a lab at Rockefeller University in New York, a mouse squeaks. But this is no ordinary squeak. It is a strange, complex ...

DNA contains genes that carry instructions for the manufacture of a protein. If a mutation occurs in a gene that results in a change to the sequence of DNA bases, then the structure of the protein ...

A groundbreaking study has identified how previously mysterious mutations in non-coding DNA contribute to kidney disease, ...

A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with ...

Neurogeneticists have discovered a novel genetic mutation and associated buildup of toxic proteins in the brain -- a type of buildup distinct from amyloid or tau, proteins that have long been the ...

A genetic mutation is an alteration in the genetic code found in DNA. A mutation changes the specific instructions of the ...
