A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...

A single enzyme that can generate all four nucleotide triphosphates, the building blocks of ribonucleic acid (RNA), was identified by researchers at the Institute of Science Tokyo. By using ...

A strand of RNA just 45 nucleotides long has been discovered to perform two key reactions required for self-replication. The ...

A new cell-free genomics framework isolates the primary impacts of transcription factors and establishes tuberculosis as a model for understanding how genes are regulated.

From vaccines and diagnostics to emerging gene-based therapies, RNA molecules are now central to modern medicine. But as their use continues to grow, so does a fundamental challenge: producing RNA ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

Nucleotide synthesis-the production of the basic components of DNA and RNA-is essential for cell growth and division. In most animal cells, this process depends closely on properly functioning ...

Researchers introduced a yeast enzyme, ScURA, into human cells, enabling nucleotide synthesis independent of mitochondrial ...
