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?

Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the ... made along the way -- in other words, that a base pair in one DNA molecule doesn't match the corresponding ...

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 ...

Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA ... bases now fit together perfectly (i.e., A with T and C with G), with each pair ...

DNA is negatively charged, due to the phosphate groups in its phosphate-sugar backbone, so histones bind ... eight histone proteins and about 146 base pairs of DNA (Van Holde, 1988; Wolffe ...

New crystallography images show that artificial DNA bases take on a surprisingly normal geometry when bound by polymerase. A series of rodent experiments showed that even with abundant food and water, ...

The researchers began by using a single strand of DNA, which serves as the backbone or scaffolding ... The entire process relies on the base-pair interactions in the scaffold and staple strands ...

In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure. RNA is usually single-stranded but ...

Except for identical twins, each person's DNA ... for the base, which can be an adenine (A), thymine (T), guanine (G) or cytosine (C). Bases are complementary. This means they always pair in ...
