A DNA sequence is shown. AAT - CCG - GTG Which sequence best shows the result of a substitution mutation in the DNA? AAT - CCG - GTG AAT - CCA - GTG ACA - TCC - GGT - G AAT - CAC - AGT - G
A DNA sequence AAT - CCG – GTG codes for Asparagine – Proline- Valine. Substitution mutations would be those mutations in which a single nucleotide is substituted with a different nucleotide. The correct answer is AAT - CCA – GTG because CCG changes to CCA which also codes for the proline. This means that this substitution is a silent mutation because there is no change in amino acid
