They were hardly modest, these two brash young scientists who in 1953 declared to patrons of the Eagle Pub in Cambridge, England, that they had "found the secret of life." But James Watson and ...

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 ...

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.

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

"The importance of deoxyribonucleic acid (DNA) within living cells is undisputed" (Watson & Crick, 1953). This opening sentence of James Watson and Francis Crick's second major paper, published ...

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 ...

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 ...
