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

Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...

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

Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...

The “RNA world” hypothesis proposes that the earliest life on Earth may have been based on RNA — a single-stranded molecule similar in many ways to DNA — like some modern viruses. This is because, ...

Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells. RNA molecules are real all-rounders. They transfer the genetic information from ...

Ribozymes are RNA molecules that are capable of catalyzing a chemical reaction. Ribozymes occur naturally inside cells where they play an essential role in the ribosome, joining amino acids together ...

RNA molecules are real all-rounders. They transfer the genetic information from the DNA in the cell. They regulate the activity of genes. And some of them have a catalytic effect: just like enzymes, ...

In new research published in the journal Angewandte Chemie, scientists applied a high throughput methodology to study the ribozyme in an innovative way. While work in this area has typically used ...

A ribozyme is a ribonucleic acid (RNA) enzyme that catalyzes a chemical reaction. The ribozyme catalyses specific reactions in a similar way to that of protein enzymes. Also called catalytic RNA, ...

The RNA world hypothesis implies that coded protein synthesis evolved from a set of ribozyme catalyzed acyl-transfer reactions, including those of aminoacyl-tRNA synthetase ribozymes. We report here ...
