Genetic approach of studying mutants

Post by HelloKitty » Tue Sep 22, 2009 2:47 am

What information(s) could you obtain from a genetic approach of studying mutants defective in a particular process?

This is my answer, however, I don't really think it is right.
The following information can be obtained from a genetic approach of studying mutants:
a. the potential function and importance of the protein
b. the number of genes involved in certain processes
c. the order of the genes in the process
d. the interactions between different genes (proteins)

Basically yes, but not always.

Imagine, you have family of genes differentially expressed, but if you knock-out one of them, the others might be able to partially supplement function of the knock-outed genes, so you won't get complete information by this ;)

Cis or trans? That's what matters.
