An estimated 100 million people worldwide share their genetic information with companies like AncestryDNA, 23andMe, and FamilyTreeDNA. All that DNA has been a boon to detectives, who can use the in… ...

During DNA replication, several proteins facilitate the unwinding of the DNA double helix into two single strands. Topoisomerases (red) reduce torsional strain caused by the unwinding of the DNA ...

DNA was a messy addition to genealogy, a sleepy, prim discipline of aristocratic origins in which the paper trail was sacrosanct. Just mentioning genetics on a genealogy email list could get you ...

DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus. Organisms composed of ...

DNA, or deoxyribonucleic acid, is a molecule found inside every cell in almost every living thing. It helps cells make proteins, which they need to survive, and it facilitates reproduction.

Human DNA, the molecule of inheritance, carries the entire set of instructions for making a complete person from a single fertilised egg. So once James Watson and Francis Crick revealed its ...

Exactly 66 years ago, on April 25, 1953, Francis Crick and James Watson published their famous article that showed that the shape of DNA is a double helix. They weren’t able to see DNA directly ...

The caption states a number of vaccines contain traces of human DNA. The DNA, the foundation wrote, comes from the lung tissue of “a healthy fourteen-week-old aborted Caucasian male fetus” and ...

Using modern DNA sequencing technology, Huang and his colleagues have conclusively verified paternally-inherited mitochondrial DNA in 17 individuals spanning three unrelated families.

Company scientists were eventually able to analyze the species' genome — or its entire DNA set. Then they used CRISPR, a gene-editing technology, to genetically modify cells from a living gray wolf.

If complete DNA could be extracted from the fossil, then it would much more likely be from a modern source than a creature that lived 80 million years ago. Scientists are optimists.
