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).

Prehistoric Genome Pushes Back Origins of Treponemal Diseases in the Americas

Scientists have recovered a genome of Treponema pallidum – the bacterium whose subspecies today are responsible for four treponemal diseases, including syphilis – from 5,500-year-old human remains in Sabana de Bogotá, Colombia.

USU Researchers Discover CRISPR Cas12a3's Potential for Viral Protein Inhibition

Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to disable and modify genes, heading off infections at the (cellular) pass.

Dual Genetic Mutations Drive RNA Mis-Splicing and Leukemia Progression

Treating acute myeloid leukemia (AML) depends on knowing what goes wrong inside cells. A new study suggests that two genetic mutations – IDH2 and SRSF2 – work cooperatively to mis-splice RNA messages and change how blood cells develop.
