Two large classes of GTPase switch proteins are used in signal transduction pathways:

1. Heterotrimeric G proteins

2. Monomeric G proteins

#Unit 8. Inheritance Biology

Steps in determining gene order in a three-point cross 

Identify the non-recombinant progeny

Identify the double-crossover progeny

Compare the phenotypes of double-crossover progeny with the phenotypes of non- recombinant progeny

The characteristic that differs between the double crossover and the non-recombinant progeny is encoded by the middle gene

#Unit 3. Fundamental Processes

SR proteins are involved in exon definition in which they interact with U1 and U2AF forming commitment E complex.
