How micro rna control gene expression
WebMicroRNAs (miRNAs) are small RNA molecules, ∼ 22 nucleotides long that can negatively control their target gene expression posttranscriptionally. There are currently more than 460 human... Web13 okt. 2016 · The finding that small non-coding RNAs (ncRNAs) are able to control gene expression in a sequence specific manner has had a massive impact on biology. Recent improvements in high throughput sequencing and computational prediction methods have allowed the discovery and classification of several types of ncRNAs.
