Self-building RNA strand may expose how life on Earth truly began
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 ...
Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint ...
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, ...
RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...
Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...
A strand of RNA just 45 nucleotides long has been discovered to perform two key reactions required for self-replication. The ...
