In the microarray cancer analysis activity, Gene 1 appeared red (expressed only in cancer cells), while Gene 3 appeared green (expressed only in normal cells). Why would Gene 1 be a better drug target than Gene 3?

GGG and GGC are codons for the amino acid, glycine. A mutation caused the insertion of a cytosine in place of the third guanine during DNA replication. Over many generations the DNA changes so that the frequency of GGC is similar to that of GGG. What effect does this mutation have on the population’s mean fitness?
