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 of individuals belonging to the same species that live in a defined A? 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 RNA se 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. DNA partitions to the ________aqueous phase, denatured proteins partition to the ______ phenol organic phase. upper; lower lower; upper

Explanation / Answer

question 34- ans is A

genome refers to genetic material of a organism.

gene pool refers to total genetic material of a population.

chromosome complement is term used for particular species.

breeding unit and race are not related to genetic material.

question 35-

the answer is population as it is apt definition for this term.

cohort belongs to taxonomic class.

hybrid is a cross breed.

pool and pod are unrelated.

36 question - ans in E as high pressure results in degradation of dna..

38 question- silver chloride cannot be used as it is insoluble in water.

39 question- A because water is less denser than organic phase.

37 question- D for DNA and 2 for RNA.
