Chapter 28, Problem 28.12P

(a)

Interpretation Introduction

Interpretation:

The structural formula of the nucleotide $\text{2'}$-deoxyadenosine $\text{5'}$-triphosphate (dATP) has to be drawn and its net charge at $\text{pH-7}\text{.4}$ has to be estimated.

Concept Introduction:

The Nucleotide consists of the Nitrogenous base, Sugar molecule and Phosphate ion.  The Nitrogenous base and Sugar molecule are linked by β-N-glycosidic bond.  The Sugar molecule and phosphate ion are linked by ester bond.  The base and sugar molecule are said to be Nucleoside.

(b)

Interpretation Introduction

Interpretation:

The structural formula of the nucleotide Guanosine-$\text{3'}$-monophosphate (GMP) has to be drawn and its net charge at $\text{pH-7}\text{.4}$ has to be estimated.

Concept Introduction:

The Nucleotide consists of the Nitrogenous base, Sugar molecule and Phosphate ion.  The Nitrogenous base and Sugar molecule are linked by β-N-glycosidic bond.  The Sugar molecule and phosphate ion are linked by ester bond.  The base and sugar molecule are said to be Nucleoside.

(c)

Interpretation Introduction

Interpretation:

The structural formula of the nucleotide $\text{2'}$-deoxyguanosine $\text{5'}$-diphosphate (dGDP) has to be drawn and its net charge at $\text{pH-7}\text{.4}$ has to be estimated.

Concept Introduction:

The Nucleotide consists of the Nitrogenous base, Sugar molecule and Phosphate ion.  The Nitrogenous base and Sugar molecule are linked by β-N-glycosidic bond.  The Sugar molecule and phosphate ion are linked by ester bond.  The base and sugar molecule are said to be Nucleoside.
