In the Watson-Crick DNA base pairing model, Adenine (A) binds to thymine (T), guanine (G) binds to cytosine (C).
1. Draw the structures of thymine and adenine stabilized by Watson-Crick base pair interaction.
2. Also draw the structure of the amide group of glutamine in an interaction of this T-A pair in a way that maximally satisfies the hydrogen bonding capacity of amide.
. Pancreatic deoxyribonuclease I (DNase I) is a nuclease that makes
single-strand nicks on double-stranded DNA. It has been observed
that treatment of nucleosomal core particles with DNase I yields a
peculiar result. When DNA from such a digestion is electrophoresed
under denaturing conditions, the single-stranded fragments are
observed to occur in a regular periodicity of about 10 bases. Suggest
an explanation of this result in terms of the structure of the nucleo-
some.

- This is DNA. Locate the nitrogen bases (nitrogens are blue). Where are they located in the molecule?Locate the sugars and phosphates, and describe their location. Adjacent nucleotides are linked by covalent phosphodiester bonds (-O-P-O-) produced by a condensation reaction. What parts of the adjacent nucleotides are linked by phosphodiester bonds?Two nitrogenous bases extending towards the middle of the double helix. Are there any covalent bonds between these bases?If there are no covalent bonds between these bases, what other kinds of bonds might hold the two strands of the double helix together?arrow_forwardAlpha polypeptide (ADH1A). Give a detailed description of its role in the disease. Describe the impact of the disease on society.Describe a way in which your gene can be manipulated to treat the disease.

Structure-Function Relationships in Genes 1. Consider the "two-line model" of a gene shown below - each line represents one strand of a DNA double helix, and the transcription start site is indicated as +1. Use the two-line models provided when answering the following questions. 3' 5' +1 Assume that you know RNA polymerase will move to the right during transcription. On the diagram above, do the following: • Label "upstream" and "downstream" on this gene • Label where you would find the promoter min I • Draw a box where you would expect to find the TATA box • Draw a third line below the model representing the RNA transcript (label the ends!) • Label one of the DNA strands as the template strand 3' 2. Now, let's try that again! This time assume that you know RNA polymerase will move to the left during transcription.
