Question

_____ is based on the new discovery that environmental factors tend to alter gene functioning without affecting the molecular structure of DNA at all by activating or deactivating particular aspects.

Answer 1

The given blank can be filled with epigenetics.

Step-by-step explanation:

The study of heritable modifications in gene expression, which do not comprise modifications in the underlying sequence of DNA is known as epigenetics. It involves a change in phenotype without modification in genotype, this, in turn, influences how the cells read the genes. The epigenetic modification is a natural and regular phenomenon that can also be affected by many other elements like the environment, age, and the disease state.
