A) Gα, Gβ and Gγ all can bind and hydrolyze GTP B) C) D) E) 22. How would expression of a mutant version of M ­cyclin that cannot be phosphorylated by M ­Cdk affect cell cycle progression? A) B) C) D) E) Upon activation by GPCR, Gα, Gβ and Gγ may dissociate into individual monomeric subunits GPCR functions as a GAP for trimeric G ­proteins One ligand ­bound GPCR can activate multiple trimeric G proteins After activation by GPCR, trimeric G ­protein remains bound to GPCR Failure to enter M phase Failure to undergo metaphase to anaphase transition Failure to exit M phase More than one round of chromosomal DNA replication per cell cycle No effect Fill in the blank with one or a small number of words (2 points each) _____________________________________________________________________________________ There is little to no Cdk activity during ____________late M and early G1___________________ _____________________________________ phase of the cell cycle and this all...
