They have no impact on gene expression.

They regulate gene expression patterns that determine cell differentiation and function.

They only affect physical traits, not gene expression.

They are solely responsible for genetic mutations.

Genetic mutations change the DNA sequence, while epigenetic changes affect gene expression without altering the DNA sequence.

Genetic mutations are reversible, while epigenetic changes are permanent.

Genetic mutations occur only in somatic cells, while epigenetic changes occur in germ cells.

Genetic mutations are caused by environmental factors, while epigenetic changes are solely genetic.

Yes, some epigenetic changes can be reversed, allowing for potential therapeutic interventions.

No, epigenetic changes are permanent and cannot be altered.

Yes, but only in certain organisms, not in humans.

Yes, but it requires extensive genetic modification.

Environmental factors can lead to epigenetic changes that affect gene expression.

Environmental factors have no impact on gene expression.

Environmental factors only affect physical traits, not gene expression.

Environmental factors can only influence genetic mutations.
