One of the mysteries of the English language finally explained.
A cellular RNA fragment that prevents the production of a particular protein by binding to and destroying the messenger RNA that would have produced the protein.
- ‘In molecular biology, microRNAs are clearly one of the top two or three discoveries of the past decade.’
- ‘Research reported in The Plant Cell shows that microRNAs control the accumulation of transcription factor proteins that regulate the expression of genes in the auxin response pathway.’
- ‘X and Y could be microRNAs, transcriptional regulators or other proteins, or the smallest molecules and ions.’
- ‘In the cross of the egg-parent (species E) to a different species the lack of a microRNA specific to a transposon expressed in the G parent prevents transposon suppression, triggering genomic instability.’
- ‘By then, scientists had proposed that plant microRNAs control protein production by glomming onto messenger RNAs, an essential intermediate in the creation of a protein.’
