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.
This DNA has suffered a mutation, either through mis-copying (when its parent cell divided), or through the damaging effects of exposure to radiation or a chemical carcinogen.
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 ...
As opposed to gene-level mutations, mutations that alter longer stretches of DNA (ranging from multiple genes up to entire chromosomes) are called chromosomal mutations. These mutations often have ...
Only around two percent of the human genome codes for proteins, and while those proteins carry out many important functions ...
In a lab at Rockefeller University in New York, a mouse squeaks. But this is no ordinary squeak. It is a strange, complex ...
A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with ...
A groundbreaking study has identified how previously mysterious mutations in non-coding DNA contribute to kidney disease, ...
Researchers uncovered unexpected patterns of mutation inheritance in the trees, revealing that some DNA damage persists unrepaired. In the case of blood stem cells, this can be for two to three years.

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