State whether the mutation is missense, nonsense, frameshift, or silent. B. Write the codon change that occurs for the missense, nonsense, and silent mutations (ex. GAA -- GAT). C. For frameshift mutations, write out the entire mutant sequence with each codon clearly indicated (if the frameshift creates a new stop codon, end the sequence at the new stop). Using the wild type DNA sequence above as a guide : Write the amino acid sequence of the mutants. Mutant 1: transition at nucleotide 23 Mutant 2: T --> G transversion at nucleotide 29 Mutant 3: an insertion of “A” after nucleotide 14
You have the following DNA coding sequence of a wild-type allele:
5’-ATG TTC CAG CTA GAT GAT ATG CTG GTA ATT GGG GAA CGC GCG CGG TAA-3’
For each of the following mutations:
A. State whether the mutation is missense, nonsense, frameshift, or silent.
B. Write the codon change that occurs for the missense, nonsense, and silent mutations (ex. GAA -- GAT).
C. For frameshift mutations, write out the entire mutant sequence with each codon clearly indicated (if the frameshift creates a new stop codon, end the sequence at the new stop).
Using the wild type DNA sequence above as a guide :
Write the amino acid sequence of the mutants.
Mutant 1: transition at
Mutant 2: T --> G transversion at nucleotide 29
Mutant 3: an insertion of “A” after nucleotide 14
Mutant 4: transition at nucleotide 7
Mutant 5: An insertion of GG after nucleotide 40
Mutant 6: transition at nucleotide 15
Mutant 7: a deletion of nucleotide 25
