A) replacement of a nonfunctional globin gene with a globin pseudogene
B) substitution of a drought-resistant gene from potato plants with a drought-resistant gene from a cactus species
C) introduction of a human WEE1 gene into a yeast culture with wee1^- mutants
D) replacement of a cdc25^- with a cdc13+ gene to rescue a cell cycle dysfunction
E) use of Drosophila heat shock gene promoters to regulate heat shock genes in fugu
