17. All DNA mutations in which a single letter of DNA is mistakenly replaced by a different single letter, and which occur between the promoter and the terminator of a eukaryotic gene, will result in an analogous change to the mRNA sequence made from that gene. 18.All DNA mutations in which a single letter of DNA is mistakenly replaced by a different single letter, and which occur between the promoter and the terminator of a eukaryotic gene, will result in an analogous change to the protein made from that gene. 19. All DNA mutations that involve the insertion of extra DNA nucleotides that were not previously a part of the sequence (and which do not remove or change any of the existing DNA sequence), and which occur between the promoter and the terminator of a eukaryotic gene, will result in a frameshift mutation. 20. Changing a single letter of DNA to a different letter is equally likely to result in a change to one amino acid in a prokaryote or a eukaryote if that single letter change occurs between the start and stop codons of a gene.
