Question
Which term is given to the total genetic information carried by all members of a population? gene pool genome chromosome complement breeding unit race _____is a group belonging to the same species that live in a defined geographic area and actually or potentially interbreed. Population Cohort Hybrid Pool Pod Many different methods and technologies are available for the isolation of genomic DNA. All methods involve except which one below? Disruption and lyses of the starting material treatments with proteinase and RNAse Separate DNA From Crude Lysate by organic extraction or salting out (via protein precipitation by salt) Removal of proteins and other contaminants DNA precipitation via ethanol or isopropanol, and DNA recovery Run through HPLC gel filtration column Measuring the intensity of absorbance of the DNA solution at wavelength 260nm & 280nm is used as a measure of DNA purity. At what A260/A280 ratio, it shows good DNA purity? 0.6 1.0 1.4 1.8 Which below cannot precipitate protein so DNA can be separated by salt out? sodium chloride potassium acetate ammonium acetate ammonium sulfate silver chloride Traditionally, phenol: chloroform is used to extract DNA. When phenol is mixed with the cell lysate, two phases form.
