Answer #1

Codons are three nucleotides that code for an amino acid. frame-shift mutations are mutations which changes the reading frame of the gene, due to the insertion or deletion of one or two nucleotides, the changes the codons downstream to the mutation, so the amino acids sequence changes from the point down-stream to the insertion or deletion, so the reading frame changes downstream to the point of mutation.

so the answer is c) addition or deletion of one or two nucleotides causes the codons to be off the pattern and therefore the mutation

    The gene encoding protein Bog in E. coli has been changed by a point mutation in its open reading frame. Originally the gene encoded a 108 amino acid long functioning protein whose amino acid composition favored nonpolar and negatively charged amino acids. After the mutation it encodes a 110 amino acid long non-functioning protein that is now rich in polar uncharged amino acids and positively charged amino acids. Which mutation scenario best explains this observation. A) A frame-shift caused by...

    QUESTION 20 In a haploid, a nonsense suppressor su1 acts on mutation 1 but not on mutation 2 or 3 of gene P. An unlinked nonsense suppressor su2 works on P mutation 2 but not on 1 or 3. Explain this pattern of suppression in regard to the nature of the mutations and the suppressors. The mutations are likely frameshift mutations, resulting in three possible proteins. The suppressor mutation may be specifically complementing the protein shape of one mutant but...
