Answer:
1. silent mutation
2. non sense mutation
3. missense mutation
Explanation:
1. <u>in a silent mutation</u>, the substituted base will code for <em>another</em> codon that will get translated to the <em>same</em> amnio acid
2. <u>in a non sense mutation</u>, the substituted base will code for a <em>STOP</em> codon that would cause the production of a faulty, usually non functional protein, <em>missing</em> some amnio acids.
3. in a missense mutation, the substituted codon codes for a <em>different</em> amino acid and this can have a small to great effect on the product protein based on its function. eg: sickle cell anemia where you've substituted a polar amino acid with a non polar one, thus causing severe consequences
