What is Normal role of Micro RNA is and explain in detail?
MicroRNA (abbreted miRNA) is a small non-coding RNA molecule (containing about 22 nucleotides) found in plants, animals, and some viruses, that functions in RNA silencing and post-transcriptional regulation of gene expression.miRNAs (microRNAs) are sho non-coding RNAs that regulate gene expression post-transcriptionally.
