Proteins differ in the amount of hydrophobic amino acids that are present on their surface. This difference can be exploited in salt fractionation but can also be used in a higher resolution method using hydrophobic interaction chromatography (HIC).

There are 4 genes (I, Z, Y, A), 2 Promoters and 3 lac operators in Lac operon

The major O1 lac operator lies adjacent to promoter

The O1 operator extends from position -5 just upstream of the mRNA start point to position +21 within the transcription unit.
