Epigenetic Barriers: Biological mechanisms that control gene expression without altering the underlying DNA sequence, which can be challenging to overcome in cloning.
Biomedical Research Models: Animals or cell cultures used in scientific studies to understand human diseases and test potential treatments.
Genetically Uniform: Possessing identical genetic material, which is crucial for controlled scientific experiments to reduce variability.
