Question

Base changes in RNA molecules do not have evolutionary consequences because RNA is not hereditary material. Consequently, errors made by RNA polymerase are less serious than errors made by DNA polymerase. This is reflected by the general lack of proofreading activity in RNA polymerases. Promoter sequences, protein-coding genes, and CRMs are all DNA sequences, and changes to bases in those regions can have evolutionary consequences. Changes in the protein coding gene can change the amino acids that are in the final protein, and may change the protein function. Changes to the other regions can affect how their genes are regulated.
