WebNov 14, 2024 · RNA editing occurs either during transcription or post-transcriptionally and involves deaminases, nucleases, ligases, and/or polymerases. It affects mRNAs, tRNAs, rRNAs, and even miRNAs, ncRNAs, and retrotransposons. When RNA editing is extensive, original DNA templates may become unrecognizable. First described in Trypanosoma … WebGenes encode proteins, and the user on build proteins are decoded in two steps: first, a messenger RNA (mRNA) molecule is produced through the transfer of DNA, and next, the mRNA serves like a template for protein production through the process of translation. The mRNA determine, in triplet code, one amino acid sequence of proteins; that codes is then …
