Q: With regard to the experiment described in Figure 9.2,
With regard to the experiment described in Figure 9.2, answer the following: A. List several possible reasons why only a small percentage of the type R bacteria was converted to type S. B. Explain w...
See AnswerQ: In Noll’s experiment of Figure 10.11, explain where DNase
In Noll’s experiment of Figure 10.11, explain where DNase I cuts the DNA. Why were the bands on the gel in multiples of 200 bp at lower DNase I concentrations? From Figure 10.11:
See AnswerQ: When chromatin is treated with a salt solution of moderate concentration,
When chromatin is treated with a salt solution of moderate concentration, the linker histone H1 is removed. A higher salt concentration removes the rest of the histone proteins. If the experiment of F...
See AnswerQ: Let’s suppose you have isolated chromatin from some bizarre eukaryote with a
Let’s suppose you have isolated chromatin from some bizarre eukaryote with a linker region that is usually 300–350 bp in length. The nucleosome structure is the same as in other eukaryotes. If you dig...
See AnswerQ: The technique of DNase I footprinting is described in Chapter 21.
The technique of DNase I footprinting is described in Chapter 21. If a protein binds over a region of DNA, it will protect the DNA in that region from digestion by DNase I. To carry out a DNase I foot...
See AnswerQ: How does the binding of a protein to DNA influence the ability
How does the binding of a protein to DNA influence the ability of DNase I to cleave the DNA?
See AnswerQ: In the technique of DNase I footprinting, the binding of a
In the technique of DNase I footprinting, the binding of a protein to a region of DNA protects that region from digestion by DNase I by blocking the ability of DNase I to gain access to the DNA. In th...
