One lab finds that a similar method produces large genetic deletions when performed in mouse embryos.

The DNA-cutting enzyme used in the technique is not as precisely targeted as scientists had thought, and investors take notice.

Four ways to study mutation rate, a crucial statistic in studies of evolution

Scientists extend the capabilities of the CRISPR-Cas system to include precise manipulations of RNA sequences in human cells.

The deadly fungus Cryptococcus deuterogattii harbors a genetic tweak that propels its mutation rate and allows it to rapidly develop antifungal resistance.

Using directed evolution, researchers selected a DNA polymerase to copy RNA into DNA.

Mutations in a cancer gene could account for some cases of disfiguring blood vessel abnormalities, scientists show.

Two mutations in a gene involved in telomere extension reverse the gene’s epigenetic silencing.

The virus that causes AIDS can replicate and mutate in the brain as early as four months after initial infection, according to a new study.
