Using RNAi. We are now able to silence any gene in almost any organism, enabling us to perform reverse genetics to analyze our gene. Sodium azide (NaN₃), a chemical commonly used to cause a transition from an AT to a GC was used on our gene. Sodium azide functions in chemical inhibition of DNA repairs, often creating a base substitution. These changes can result in various mutations including silent, missense, nonsense, or frameshift mutations. In the DNA sequence, high impact mutations were targeted in the coding regions, splice sites, and donor sequences.
