Question

Consider the following two mRNA molecules:         ACGUGUACCG         ACGUUGUACC The difference between the two molecules would most likelyresult in which type of change in the resulting proteinmolecule? a) no change in the protein b) a silent mutation c) frameshift mutation, resulting in a change in the aminoacid sequence d) deletion mutation, resulting in a change in the amino acidsequence e) splicing Consider the following two mRNA molecules:         ACGUGUACCG         ACGUUGUACC The difference between the two molecules would most likelyresult in which type of change in the resulting proteinmolecule? a) no change in the protein b) a silent mutation c) frameshift mutation, resulting in a change in the aminoacid sequence d) deletion mutation, resulting in a change in the amino acidsequence e) splicing

Explanation / Answer

D a deletion mutation, because the U in the top sequence was deleted which caused the bottom row to be off sequence by one, resulting in a change in the amino acid sequence
