question 132

Multiple Choice

Mapping studies have showed that within a group of mutants with the same growth requirements (i.e., the same overt phenotype) , individual mutations are on different chromosomes.This indicates that

• C) different genes govern the same step in a particular biological pathway.
• D) all biological pathways are governed by different genes.
• E) genes do not govern steps in biological pathways, but proteins do.
