Answer:
Epigenetics.
Explanation:
Epigenetics is the study of phenotypic changes which are heritable but not related to changes in the DNA sequence. It is influenced by several factors including the environment.
An example of epigenetics is DNA methylation: addition of methyl group to some part of the DNA that prevents that part from being expressed. Other examples include history modifications.
In summary, Epigenetics describes inheritance through other mechanisms than through the DNA sequence.
Proteins-proteases
Carbohydrates- amylase
Fats-bile
