Because of this flexibility, the 30 to 40 tRNAs present in a cell can "read" all 61 codons in mRNA ... their structure is concerned, these RNAs all share the same basic single-stranded chemical ...

Researchers at the University of Cologne and University Hospital Cologne have determined that the novel mRNA-based COVID-19 ...

To add multiple polyA tails to the mRNA backbone and create the branched structure, the scientists used click chemistry, which is a set of reactions used for joining two molecular entities. Additional ...

The central dogma of molecular biology suggests that the primary ... However, in the half-century since the structure of DNA was first elaborated, scientists have learned that RNA does much ...

This image highlights two alternatives for the ribosome to be recruited to an mRNA that is still being synthesized by RNA polymerase (RNAP). RNAP (left, red) can directly deliver the mRNA to the ...

the mature mRNA is transported from the nucleus to the cytoplasm, where it serves as a template for protein synthesis. Some RNA molecules, called ribozymes, possess catalytic activity and can catalyze ...

She has a PhD in systems biology from ETH Zurich and a master’s in molecular biology from Utrecht University ... staining techniques to establish that both RNA-binding proteins and mRNA are ...

RNA breaks destined for repair are inflicted by sequence-specific or structure-specific endoribonucleases during physiological RNA processing (e.g. tRNA splicing; kinetoplast mRNA editing ... 5’-OH ...

Both uracil and thymine pair with adenine, but they differ in their chemical structure. Thymine has an additional methyl group (-CH3) attached to its pyrimidine ring, while uracil lacks this group.

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors ... "The largely stable structure of the ...

Researchers have discovered that mRNA-based COVID-19 vaccines have a persistent effect on the innate immune system. These mechanisms may help the human body to better protect itself against potential ...
