High-tech replicas, also known as clones, are artificially created copies of living organisms or objects. They are created using advanced technology and are often used for research purposes. Clones are created by taking a sample of the original organism or object and then using that sample to create an exact replica. Clones can be used to study the effects of certain treatments or to create new products. Clones can also be used to replace lost or damaged parts of an organism or object.
