Consider the following portion of mRNA produced by the normal order of DNA nucleotides:
5'ACA | UCA | CGG | GUA3'
a. Write the amino-acid sequence that would be produced from this mRNA.
b. Write the amino acid sequence if a mutation changes UCA to ACA. Is this likely to affect protein function?
c. Write the amino acid sequence if a mutation changes CGG to GGG. Is this likely to affect protein function?
d. What happens to protein synthesis if a mutation changes UCA to UAA?
e. What happens to the protein sequence if a G is added to the beginning of the chain and the sequence changes to 5'GAC | AUC | ACG | GGU3'?
f. What happens to the protein sequence if the A is removed from the beginning of the chain and the sequence changes to 5'CAU | CAC | GGG3'?
