Question

Match the following using the GENETIC CODE: 3) Below are descriptions of several different mutations. Match each with the one term (write lotters A-F) that would be the best classification for this mutation. You may use the tems once, more than once, or not at all. (3 pts.) A mutation changes a G to a C within an intron A mutation changes a UCA codon to UCG A mutation changes a UCA codon to CCA A mutation changes a UCA codon to UAA This kind of mutation changes every amino acid in the protein beyond the point where it adds an extra nucleotide Iv. V. A. Missene mutation B. Nonsense mutation C. Antisense mutation D. Silent mutation E. Insertion mutation F. Deletion mutation Of the above listed mutations (I-V), which one(s) can be categorized under frameshift mutation?

Explanation / Answer

1- D since introns are non coding , any change wont affect the final protein expression.

2-D since UCA and UCG code for same amino acid , it is a silent mutation.

3-A since UCA codes for serine and CCA codes for proline , this is a missense mutation.

4- BUAA is a stop codon , therefore terminatiom of further protein expression , hence a silent mutation

5- E insertion mutation.

V is a type of frame shift mutation.
