<prompt> Which of the following doesnt occur during the processing of RNA?Terminal additionNucleoside modificationNucleoside cleavageChemical hydrolysis  <response>: Precursor tRNA is processed to form mature tRNA. Alterations during processing are of three types: nucloelytic reactions, nucleoside modifications, terminal additions of nucleotides. Chemical hydrolysis is not a pa of RNA processing. Poly A tailing and 5capping occurs in the processing of RNA. Methylation and deamination are known to occur. Introns will be removed after cleavage in the process.
