For a protein-DNA binding reaction with ΔH = 0, sketch the van’t Hoff plot, label both axes.
Rank the following in terms of predicted rates: the nucleation of an α helix;the nucleation of a parallel β sheet; the nucleation of an antiparallel βsheet. Justify your predictions.
When Griffith incubated heat-killed virulent S strain bacteria with live avirulent R strains, he found that R cells were transformed into lethal, disease-causing bacteria. What is the molecule responsible for the transformation of R cells into the S type? Why did the transformation occur?
A. Proteins in the heat-killed S cell extract; they were able to synthesize the capsular polysaccharide in the R cells and make them virulent.
B. The capsular polysaccharide in the heat-killed S cell extract; the polysaccharide was able to attach to R cells, thus making them virulent.
C. DNA in the heat-killed S cell extract; the DNA altered the genetic makeup of R cells, allowing them to synthesize the polysaccharide capsule, thus making them virulent.
D. Specialized lipids in the cell membrane of the S cells were able to integrate with the R cells, conferring the ability to evade host immunity.
