What is microRNA? Special class Post-Transcriptional Regulators


What are microRNAs? MicroRNA is a class of post-transcriptional regulators. They are short ~22 nucleotide RNA sequences that bind to complementary sequences in the 3’ UTR of multiple target mRNAs, usually resulting in their silencing. MicroRNAs target ~60% of all genes, are abundantly present in all human cells, and are …
