Why is it important that the alcohol used in the DNA extraction is kept cold? Helps to precipitate the proteins at the interface between the aqueous and alcohol layers, as the solubility of any compound is reduced at lower temperatures. The colder the temperature of alcohol, the greater the yield. Helps to precipitate the DNA in the aqueous layer, as the solubility of any compound is reduced at lower temperatures.

In the protocol for extracting DNA, what is the purpose of the clear shampoo in the DNA extraction buffer? In the protocol for extracting DNA, what is the purpose of the clear shampoo in the DNA extraction buffer? Shampoo contains detergents, that help to break down lipids in cell walls, thus freeing the DNA. Shampoo contains detergents, that help to break down proteins in cell membranes, including the nuclear membrane, thus freeing the DNA. Shampoo contains salts, that help to break down lipids and proteins in cell membranes, including the nuclear membrane, thus freeing the DNA. Shampoo contains detergents, that help to break down lipids in cell membranes, including the nuclear membrane, thus freeing the DNA.
A plot showing the % of denautration as a function of temperature for a melting point of a DNA sample under 0.12 M NaCl gives an equation of a line of Y= 0.0074 X - 0.044 (Where Y is the % of denautration and X is the temperature in degree C) This is all the information that was given. 1. Calcuate the melting point of this DNA in degree C

PCR is a molecular biology technique where template DNA is amplified using a primer and oligonucleotides. The reaction is catalyzed by a thermostable DNA polymerase and in a particular reaction, the template strands are denatured at 95˚C. For strand hybridization, the melting temperature is 55˚C. What do you predict about the average duration of H bonds at the high temperature in comparison to the low temperature?
Equilibrium Density Gradient Centrifugation of DNA Samples Review the following terms using the internet before working on the problem: radioactive labeling, DNA, cesium chloride, equilibrium centrifugation, DNA denaturation using heat EXPERIMENT Radioactively labeled bacterial DNA was analyzed by cesium chloride (CSCI) equilibrium density gradient centrifugation. The radioactivity of fractions collected from the gradients, and the densities of the two peak fractions, were determined. Graph A: Native DNA sample; Graph B: DNA sample heated to 100°C and rapidly cooled on ice before centrifugation.
