Question

A mutation causing an addition or a deletion of one base pair resulted in the production of a nonfunctional mutant protein. The sequences of the normal and mutant proteins are given below. Normal: Met – Leu – Ala – Thr – Gln Mutant: Met – Leu – Ala – His – Pro – Ile – Glu – Ser – Thr – ….. Was this mutation cause by an insertion or a deletion? Answer Below, fill in the codons in the coding sequence of the mRNA that is translated into the mutant protein. If more than one codon is possible, just enter a single codon.

    Answer:

    Caused by insertion  of codons;

    Codons:  as 5′ AUG UUG GCU CAC CCA AUA 3

    Explanation:

    1. This mutation is the type of addition mutation ,in which extra codons are inserted in the codon sequence, which codes for amino acids, finally protein will contain extra amino acids.

    2. In this case, there is the insertion of these codons which codes for amino acids named as:

    AUA (Ile/I) Isoleucine,

    CCA (Pro/P) Proline;

    CAC (His/H) Histidine;

    GCU (Ala/A)Alanine;

    UUG (Leu/L) Leucine;

    AUG (Met/M) Methionine.
