The Mfp factor is present in meat, fish, and poultry that enhances the absorption of non-heme iron that's in the same foods or in other foods eaten at the same time.
I'm not sure what you're asking, but if you're looking for a word to describe this change its "mutation"
DNA is the genetic composition of the cells in the human body, think of it as the coding for a computer but for cells. These carry your genetic composition (blue eyes, Brown hair, tall, short blah blah blah) and traits like smart, funny, shy.
Hope that helps.
