What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic ...

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases.

The landmark ideas of Watson and Crick relied heavily on the work of other scientists. What did the duo actually discover? Many people believe that American biologist James Watson and English ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

Francis Crick and James Watson with a model of the DNA molecule At midday on 28 February 1953, Francis Crick and James Watson walked into The Eagle pub in Cambridge and announced “We have ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

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 ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus, the ...
