Three major types of RNAs are mRNA, rRNA, and tRNA. For each of the conditions below, predict the consequences in terms of the population of proteins being synthesized in a particular cell.
 
  What qualitative and quantitative changes, if any, are expected in the individual protein involved (if one is involved) and in the population of proteins in this cell?
  (a) a frameshift mutation in the heterozygous state
  (b) a deletion of a significant proportion of ribosomal genes (rDNA)

(a) Population of proteins: Half of the protein products of that gene will be defective, and the other half will be normal. Individual protein: The protein should show multiple amino acid substitutions downstream from the point of the mutation. If a nonsense triplet is introduced, the protein will be shortened in the substituted region.
(b) Population of proteins: There would be an overall reduction in protein synthesis. Individual proteins: All of the proteins would be made in their normal form but at reduced levels.
