Question

Quizplus · Accepted Answer

Epigenetic regulation refers to modifications to DNA that do not alter the underlying sequence but can impact gene expression. This can lead to changes in an individual's phenotype without any changes to the DNA itself. Feedback loops, genetic parameterization, and regulatory cascades are other important concepts in biology but do not directly relate to epigenetic regulation.
