Web7 sep. 2015 · MicroRNAs (miRNAs) are 20–25 nucleotides in length, and are non-coding RNAs that incompletely bind to the 3′ untranslated region (UTR) of multiple target mRNAs and thereby enhance their degradation and inhibit their translation. Web3 apr. 2015 · MicroRNAs (miRNAs) repress the expression of many genes in metazoans by accelerating messenger RNA degradation and inhibiting translation, thereby reducing the level of protein. However, miRNAs only slightly reduce the mean expression of most targeted proteins, leading to speculation about their rol …. Gene expression.
