How micro rna control gene expression
Web21 sep. 2024 · The miRNA or microRNA are tiny (22 to 25 nucleotides) naturally occurring molecules involved in gene control. These are the conserved sequences that have been present in all eukaryotes throughout evolution, but certain miRNAs are also found in viruses. During genetic screening, Lee et al. found the first microRNA in worms in 1993. WebFor RNAi, the 21-residue siRNA, or its longer double-stranded RNA precursor, is designed to be perfectly complementary to part of the target mRNA sequence, which leads to …
