Ligand binding to either of the two yeast pheromone GPCRs triggers the exchange of GTP for GDP on the Gα subunit and dissociation of Gα∙GTP from the Gβγ complex.

#Unit 3. Fundamental Processes

TBP causes the minor groove to be widened to an almost flat conformation; it also bends the DNA by an angle of 80. The interaction between TBP and DNA involves only a limited number of hydrogen bonds between the protein and the edges of the base pairs in the minor groove.  Instead, much of the specificity is imposed by two pairs of phenylalanine side chains that intercalate between the base pairs at either end of the recognition sequence and drive the strong bend in the DNA.

#Unit 13. Methods in Biology

Polymorphism is produced due to the complementary sequence for the primer used being

present in one strain (strain A) but not in the other (strain B). As a result, an amplification product will be detectable as a band in strain A, while strain B will not show the product.
