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

They can also appear spontaneously during the replication of DNA. Mutations generally fall into two types: point mutations and chromosomal aberrations. In point mutations, one base pair is changed.

There are many different types of mutations which can arise in DNA. This diagram shows the normal order of the bases for one of the strands in a DNA molecule. Only one of the strands of DNA is ...

Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine ...

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

According to the findings, people who carry a specific variation of this repeated DNA strand—which resides ... in repeat ...

This was particularly evident in blood stem cells, where between 15 to 20 per cent of the mutations resulted from a specific type of DNA damage that persists for two to three years on average ...

Stanford Medicine researchers sifted through thousands of single nucleotide mutations in DNA to identify fewer than 400 that are functionally associated with inherited cancer risk.

Researchers have revealed new details about the CRISPR-Cas5-HNH/Cascade complex, a variant of the type I-E CRISPR-Cas system, ...
