A strand of RNA just 45 nucleotides long has been discovered to perform two key reactions required for self-replication. The molecule, which is a kind of RNA enzyme, offers a tantalising clue towards ...

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...

Scientists are exploring how DNA’s physical structure can store vast amounts of data and encode secure information.

A DNA nano-harvester stays on its track inside tumor cells, measuring cancer aggressiveness by detecting a key microRNA ...

In May 1952, Rosalind Franklin and Raymond Gosling captured Photo 51, a crucial X-ray diffraction image revealing DNA's ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this ...

Twist Bioscience Corporation (NASDAQ: TWST), a mid-cap growth and value biotech company, today launched the Twist TrueAmp ...

Scientists on their quest to find the origin of life have stared into the primordial soup, trying to answer the ultimate chicken-and-egg question: Which came first, the genetic code or the proteins ...

Researchers have identified a molecular brake that limits DNA replication in healthy cells, revealing how cells prevent a long-suspected replication catastrophe and pointing to a potential ...

These random molecules were fed a collection of three-base-long RNAs, each linked to a chemical tag. The idea was that if a molecule is capable of ligating one of these short RNA fragments to itself, ...
