DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Study offers new insight into the link between oral microbiome and head and neck cancers

More than a dozen bacterial species among the hundreds that live in people's mouths have been linked to a collective 50% increased chance of developing head and neck squamous cell carcinoma (HNSCC), a new study shows.

Known genes account for most undiagnosed cases of developmental disorders

Scientists have conducted the largest and most diverse study to date on how recessive genetic changes contribute to developmental disorders. They found that most undiagnosed cases that are due to recessive causes are linked to genes we already know about, and suggest a shift in research focus could improve diagnosis rates.

Enhanced TnpB protein offers new possibilities for gene editing

CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissor" but is much smaller and thus easier to transport into cells.
