Messenger RNA (mRNA) is the RNA that carries information from DNA to the ribosome, the sites of protein synthesis (translation) in the cell. The mRNA is a copy of DNA. The coding sequence of the mRNA determines the amino acid sequence in the protein that is produced. However, many RNAs do not code for protein (about 97% of the transcriptional output is non-protein-coding in eukary…
WebMay 13, 2024 · siRNA is a double-stranded RNA molecule that is non-coding. It is also known as silencing RNA and short interfering RNA. It is similar to microRNA (miRNA) and the structure is short and... WebSmall interfering RNA ( siRNA) [1] is a class of double-stranded RNA molecules, 20-25 base pairs long. siRNA plays many roles, but it is most notable in the RNA interference (RNAi) pathway, [2] where it interferes with the expression of certain genes. Genes are only affected if they have nucleotide sequences complementary to those of the siRNA.
