Solution

Answer: RNA editing and differential pre mRNA splicing are two post-transcriptional modification that can lead to altered amino acid sequence of protein.

RNA editing occurs by two mechanism in mRNA firstly by changing the structures of individual nucleotide bases and secondly by inserting or deleting nucleotides at specific sites in RNA.

This RNA splicing is the process of removal of introns and joining of exons to form functional RNA.
