Transcomplementation is a name sometimes given for a test to see whether a gene from one organism can "rescue" a loss- of- function mutant of a different organism with a homologous gene. To which of the following processes might this term apply?
A) replacement of a cdc25- with a cdc13+ gene to rescue a cell cycle dysfunction
B) introduction of a human WEE1 gene into a yeast culture with wee1- mutant yeast
C) use of Drosophila heat shock gene promoters to regulate heat shock genes in the model fish, fugu
D) replacement of a nonfunctional globin gene with a globin pseudogene
E) substitution of a drought- resistant gene from potato plants with a drought- resistant gene from a cactus species

Question

Quizplus · Accepted Answer

Transcomplementation involves introducing a functional gene from one organism to rescue a mutant phenotype in another organism with a homologous gene, as in the case of introducing a human WEE1 gene into a yeast culture with a wee1- mutant.
