Chapter 4, Problem 49P
Interpretation Introduction

Interpretation:

A reasonable explanation for the relation between % of GC base pairs in DNA and the melting temperature needs to be given.

Concept introduction:

The GC base pair i.e. Guanine - Cytosine pair help the DNA to maintain its helical structure which is dependent on the nucleotide sequences. A base pair is a unit structure which contains two nucleotides connected by hydrogen bonds to each other. These nucleotide strand connected by the hydrogen bond of the base pairs are stable at room temperature, but they separate above a melting point which is defined by the length of the molecule, the extent of mispairing and the amount of GC content in it. Higher GC content makes the melting point higher.

May you please help me with this? A sample of purified DNA was incubated with deoxyribonuclease (DNAse) at 37oC. An aliquot was removed from the reaction mixture every minute for 5 minutes and the A260 recorded. The following data were obtained. Time (min) A260 0 0.60 1 0.64 2 0.67 3 0.70 4 0.72 5 0.73 Describe the action of deoxyribonuclease on DNA and explain the increase in A260.
Ethanol promotes bonding between Na+ ions from the salt and charged phosphate group of the DNA due to a higher dielectric constant than water. True or False?
Ethanol (CH3-CH2-OH) is miscible in water because it is able to form hydrogen bonds with itself and other molecules.  However, its structure only allows it to form 1-2 hydrogen bonds.  This is one reason why even low concentrations of ethanol in solution are lethal for cells.  Based on this information, explain why we can use high concentrations of ethanol to precipitate DNA out of solution. Also, describe/predict the effects of increasing concentrations of ethanol in (and around) a cell on macro-molecular interactions (i.e. on weak bonds). Finally, it is possible to select for yeast that are tolerant to increased concentrations of ethanol.  Give an example of a physiological change in yeast cells that might make them resistant to ethanol.
