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

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 ...

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 ...

The world’s most famous molecule – the DNA double helix – sometimes doubles up again. Researchers have now found this quadruple-stranded form in healthy human cells for the first time.

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.

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 ...

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 ...
