Question
Chapter 4, Problem 4P
Interpretation Introduction
Interpretation:
The percentages of all the bases in RNA that has 20 % of U should be predicted.
Concept introduction:
DNA is double-stranded helix whereas RNA is a single-stranded helix
Therefore, due to the single-stranded structure of RNA helix, base rule cannot be applied to find the percentage of the remaining base.

DNA
True or false
A long chain polymer in which the internucleotide linkages are of the diester type between C-3’ and C-5’
Hydrolyzed by weak alkali (pH 9 to 100°C)
Different from RNA since in the latter the internucleotide linkages are between C-2’ and C-5
Usually present in tissues as a nucleoprotein and cannot be separated from its protein component
Biochemist Erwin Chargaff was the first to note that, in DNA, [A] = [T] and [G]= [C], equalities now called Chargaff’s rule. Using this rule, determine the percentages of all the bases in DNA that is 20% thymine.
Reposting - What would the tertiary structure of the dipeptide Asp-Ser be if it was made into a polypeptide chain? (Would it form a beta pleated sheet, an alpha helix, etc) Why would it do this? What properties of this polypeptide causes this?
This sub part still needs to be solved - What would the tertiary structure of Pro-ala and Glycl-L-alanine be?
