Small non-coding rnas in animal development

WebApr 4, 2016 · Small non-coding RNAs (sncRNAs) are classes of short RNAs, which do not encode proteins, but rather perform regulatory functions by engaging target transcripts through sequence-specific interactions. Among these, microRNAs (miRNAs) are single-stranded molecules roughly 22 nt in length ( 1 ). WebJul 6, 2024 · NcRNAs smaller than 200 nucleotides (nt) are called small or short non-coding RNAs, whereas the ones longer than 200 nt are called long non-coding RNAs (lncRNAs). These two groups themselves are rather heterogeneous. Small ncRNAs can range from few to 200 nt, while lncRNAs have a size up to several kilobases.
