Living cells are fundamentally nonequilibrium systems, meaning they constantly spend energy through seemingly one-way, irreversible processes, such as transcribing DNA into RNA, to keep life going.

Researchers have uncovered a previously hidden layer of complexity in how genes are activated, showing that water molecules ...

Rosalind Franklin, James Watson and Francis Crick discovered the structure of DNA -- that molecular blueprint for life -- over 70 years ago. Today, scientists are still uncovering new ways to read it.

De novo genes are evolution’s magic trick—new genes appearing from non-coding DNA, much like a rabbit pulled from a hat. Once considered impossible, de novo genes have been identified in Drosophila ...

New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA. Every living cell transcribes DNA into RNA. This process begins when an ...

RNA polymerase, the enzyme that synthesizes RNA from DNA during transcription, has been captured mid-reaction for the first ...

Bacteria defend themselves from viral infection using diverse immune systems, many of which sense and target foreign nucleic acids. Defense-associated reverse transcriptase (DRT) systems provide an ...

For millennia, evolution has intrigued many great thinkers, prompting questions about how new traits emerge as species adapt over time. Then, attention shifted to natural selection and the inheritance ...

Selon les tests standards, deux personnes de groupe sanguin A sont considérées comme identiques. Pourtant, leurs globules ...

Pendant longtemps, nous avons appris à lire le génome en séparant deux mondes. D’un côté, les gènes, ces portions d’ADN qui ...
