Human cloning processes for therapeutic and reproductive uses. For therapeutic cloning, DNA is inserted into an enucleated donor egg cell, producing a blastocyst, and pluripotent embryonic stem cells are cultured for transplanting specialized cells. For reproductive cloning, the blastocyst is implanted into a surrogate, who brings the cloned infant to term.
Sheep cloning processes for therapeutic and reproductive uses. For therapeutic cloning, DNA is inserted into an enucleated donor egg cell, producing a blastocyst, and pluripotent embryonic stem cells are cultured for transplanting specialized cells. For reproductive cloning, the blastocyst is implanted into a surrogate, which brings the cloned sheep to term.

Xenotransplant process to clone cells, organs, or tissue to transplant to a sheep for therapeutic use. Pig donor egg cells have alpha 1,3 galactosyl transferase removed to reproductively clone knockout pigs, lowering cross species organ or tissue transplant rejection. Sheep DNA can also be inserted and stem cells cultured for transplanting specialized cells.

Computer generated molecular model of a hairpin ribozyme (a RNA enzyme, also known as a catalytic RNA), a small RNA molecule that can catalyze a chemical reaction. The hairpin ribozyme is one of four known natural catalytic RNA's that carry out sequence-specific cleavage of RNA. The model shows the atoms as spheres and the backbone structure as a long tube.
Illustration of a helicase enzyme separating two strands of deoxyribonucleic acid (DNA). The process of unraveling a double helix of nucleic acid strands is important to many cellular functions, such as DNA replication, RNA synthesis, RNA transcription, DNA recombination, and DNA repair.
