Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published ...

Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

Each ribboning strand of DNA in our bodies is built from stacks of four molecular bases, shown here as blocks of yellow, green, blue and orange, whose sequence encodes detailed operating ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

In a molecule of DNA, nucleotides form base pairs with a unique molecular geometry called Watson and Crick geometry, named for the scientists who discovered the double-helix structure of DNA in 1953.

Early research shows that editing expanding trinucleotide repeats halts the lengthening process that causes neurological ...

They pair up with another to form what are called base pairs. Your DNA has about 3 billion of these couples. The way they’re strung together tells your cells how to make copies of each other.

Each cell in a plant, animal, or person contains millions, or even billions, of DNA base pairs—molecules connected by hydrogen bonds that are the building blocks of DNA. These base pairs ...

To get around that problem, forensic experts have to focus on an extremely tiny portion of non-identical DNA, called short tandem repeats (STR). These are two to five base pairs of repeated ...
