Among mammals, lactase persistence is unique to humans — it evolved relatively recently (in the last 10,000 years) among some populations, and the majority of people worldwide remain lactase nonpersistent.
Lactose is inhibiting the repressor, allowing the RNA polymerase to bind with the promoter, and express the genes, which synthesize lactase.
Eventually, the lactase will digest all of the lactose, until there is none to bind to the repressor.
Humans are born with high levels of lactase expression.
In humans, it requires a special enzyme ( lactase ) for disassembly during digestion.
It is broken down when consumed into its constituent parts by the enzyme lactase during digestion.
