begin at the codon TAG and ends at the codon ATT
begin at the codon ATT and ends at the codon TAG
begin at the codon AGC and ends at the codon ATT

The two sequences below is of an original mRNA and one that has a silent mutation. Explain why this mutation is considered silent.
AUG-GCU-UUU-CAA-UAA
AUG-GCU-UUC-CAA-UAA
Can a deletion or insertion in the codon be deleterious (dangerous)?
No, a deletion or insertion is never negative
Yes, a deletion or insertion can create a protein that is not functional
