Since 1869, scientists had known about DNA, but its structure remained elusive until 1953. Understanding its shape would help explain how the life-generating molecule worked.

DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Check your ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

The Discovery of DNA's Structure: 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 ...

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 ...

First Look: DNA Replication For the first time ever, scientists have captured a single DNA molecule replicating on video — and it’s changing the way we think about the entire process. One of ...

During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder.

DNA is a vitally important molecule for not only humans but also most other organisms. DNA contains our hereditary material and our genes, the things that make us unique.

A predictive biophysical model that integrates protein-DNA structures and sequences to accurately determine genomic binding sites and affinities of DNA-binding proteins.

Researchers at Washington University School of Medicine in St. Louis have revealed the structure of a key protein involved in ...
