The G-proteins bind only to _________________(a) cytosine(b) guanine(c) thymine(d) adenineThis question was addressed to me in class test.I would like to ask this question from Cell Signaling and Signal Transduction topic in chapter Cell Signaling and Signal Transduction of Cell Biology

Answer»

Correct ANSWER is (b) guanine

The best I can explain: The G-proteins are CALLED so because they bind only to the guanine nucleotides – GTP (guanosine TRIPHOSPHATE) and GDP (Guanosine diphosphate). The protein is heterotrimeric and CONSISTS of three different polypeptides SUBUNITS.
