These mutations often, but not always cause changes to the encoded protein. Below are five examples of DNA changes. For each, enter the sequence of the mRNA that would be transcribed from the DNA and of the protein that would be translated from the mRNA. Include spaces between codons. Write amino acids in single letter code without s codon. The mRNA and protein sequences for the unaltered DNA have been entered for you.

more questions.
1. from the 5 type of DNA mutations, least change in the amino acid sequences is by- nucleotide substitution at the third position of a codon
2. single nucleotide insertion can alter an amino acid sequence, assume a polypeptide is composed of variety of amino acids- early termination
3. from the 5 type of DNA mutations, most change in the amino acid sequences is by- insertion of one nucleotide
4. if 2 nucleotide were deleted from 4th codon- most similar amount of amino acid changes- insertion of one nucleotide
