Medically reviewed by Anju Goel, MD Deoxyribonucleic acid (DNA) is the material in cells that carries all genetic information in humans, animals, plants, and all living cells. It’s passed down from ...

DNA holds the instructions that make us who we are. If we want to read those instructions, say to understand our predisposition to genetic disorders, we need to carefully 'unzip' DNA's iconic ...

During DNA replication, the classic double helix can temporarily rearrange into an alternative structure known as a DNA three ...

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

DNA evidence preserved on a microscope slide after a 1956 double homicide and the use of forensic genealogy helped a Montana sheriff's office close the books on the 65-year-old cold ...

Scientists have built a microscope capable of visualizing optical responses at the scale of individual atoms, redefining the ...

By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered that strand separation—the essential process a "resting" double helix ...

Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, mismatch repair, single-strand or double-strand break repair.
