Question

Quizplus · Accepted Answer

Epigenetic changes refer to modifications to the DNA molecule that do not alter the underlying sequence of bases. Instead, they alter the expression of genes and the traits they influence without changing the genetic code itself. Epigenetic changes can occur throughout an individual's life in response to environmental factors and can even be passed down to future generations. These changes are distinct from mutations, which involve alterations to the underlying sequence of DNA bases.
