The process of distinguishing between the following possibilities of inhibition of lac operon transcription by lac repressor either by inhibiting the binding of ribonucleic acid (RNA) polymerase to its promoter or by allowing transcription inhibition, but blocking elongation past the site of bound repressor should be determined. Concept introduction: The lac operon or lactose operon is the operon that is needed for the transporting lactose and metabolism of lactose in E.coli cell. Deoxyribonucleic (DNA) footprinting method through which sequence specifics of DNA-binding proteins in-vitro is investigated.

Arrange the four structures in order from most reduced to most oxidized. Most reduced R-CH2-CH3 R-CH2-CH₂-OH R-CH,-CHO R-CH₂-COO Most oxidized

for each pair of biomolecules, identify the type of reaction (oxidation-reduction, hydrolysis, isomerization, group transfer, or nternal rearrangement) required to convert the first molecule to the second. In each case, indicate the general type of enzyme and cofactor(s) c reactants required, and any other products that would result.
