In this type of pairing, adenine (A) forms two hydrogen bonds with thymine (T) in DNA or uracil (U) in RNA, while guanine (G) forms three hydrogen bonds with cytosine (C). These base pairs are highly ...

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 ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

The basic repeating structural (and functional) unit of chromatin is the nucleosome, which contains eight histone proteins and about 146 base pairs of DNA (Van Holde, 1988; Wolffe, 1999).

DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...

A new study suggests a far more intricate genetic tapestry is involved in the ultimate ancestry of people in Japan.

These acted like anchors. They then added specially designed DNA pieces that folded into eight-sided shapes called ...

A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA that determines what protein to produce and when, is called a gene. First established in 1985 by Sir ...

Ring-shaped extrachromosomal DNA is implicated in many cancers. Rachel Brazil talks to the scientists trying to uncover their ...

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 ...

The new pairs may also be used in a SELEX (systematic ... Such probes are sensitive, even to single base differences in target DNA. Freed from the constraint of needing hydrogen bonding to achieve ...

And each time this happens, your entire genetic library—your genome, which totals more than 3 billion base pairs of DNA—has ...
