5. Compare the mutant DNA to the original DNA strand I to answer the question. Original DNA:CGG/TAT/TCA IGAC /TAA/AAG/CTT Mutant DNA: CGG/TA IT /CAG/ACT/AA A/AGC/TT What kind of mutation is this? Insertion Inversion D Deletion Substitution

## Step 1<br />The problem involves comparing two DNA sequences: the original DNA and the mutant DNA. The original DNA sequence is: CG G/TAT/T CA/GA C/T AA/AAG/CTT. The mutant DNA sequence is: CGG/TAT ICA G/ACT/AAA/AGC/TT.<br /><br />## Step 2<br />By comparing the two sequences, we can see that the original DNA sequence has a 'T' at the 5th position, while the mutant DNA sequence has an 'I' at the same position. This indicates that the 'T' in the original DNA sequence has been replaced 'I' in the mutant DNA sequence.<br /><br />## Step 3<br />This type of mutation, where one base is replaced by another, is known as a substitution mutation. Substitution mutations can occur in two forms: silent mutations, where the change does not affect the amino acid sequence of the protein, and missense mutations, where the change results in a different amino acid being incorporated into the protein.<br /><br />## Step 4<br />In this case, the 'T' in the original DNA sequence has been replaced by an 'I' in the mutant DNA sequence, which is a clear example of a substitution mutation.
