Which best describes the benefit of transgenic organisms to society?

• Transgenic organisms can be used to identify people based on their

  DNA fingerprints.

• Transgenic organisms can be used to improve agricultural products

  and to create medicines.

• Transgenic organisms make it easier for stem cell research to occur

  without the need for embryos.

• Transgenic organisms make it easier to clone so that breeders can

  produce identical animals for sale.
