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) An acridine dye-induced mutation (adds or deletes single bases in DNA) leads to an mRNA for one protein-producing gene. The condition is heterozygous in the involved cell.
(b) A deletion (homozygous) that removes approximately half of the rRNA genes.
