The study of Neurospora mutants grown on various supplemented media enabled researchers to identify single genes involved in the arginine synthesis pathway.Why was Neurospora a better model organism than a human cell line for this study?
A) Neurospora DNA is more sensitive to X rays than human DNA.
B) The arginine synthesis pathway is less complex in Neurospora.
C) Arginine is an essential amino acid in human cells.
D) All human alleles are expressed phenotypically.
E) All Neurospora alleles are expressed phenotypically.

Quizplus · Accepted Answer

Neurospora is haploid for most of its life cycle, meaning that any mutation in a gene will be expressed phenotypically, making it easier to study gene function.
