Detailed explanation-1: -Therapeutic cloning, also called somatic cell nuclear transfer, is a technique to create versatile stem cells independent of fertilized eggs. In this technique, the nucleus is removed from an unfertilized egg. This nucleus contains the genetic material.
Detailed explanation-2: -What is therapeutic cloning? Therapeutic cloning involves creating a cloned embryo for the sole purpose of producing embryonic stem cells with the same DNA as the donor cell. These stem cells can be used in experiments aimed at understanding disease and developing new treatments for disease.
Detailed explanation-3: -In therapeutic cloning, the blastocyst is not transferred to a womb. Instead, embryonic stem cells are isolated from the cloned blastocyst. These stem cells are genetically matched to the donor organism, holding promise for studying genetic disease.
Detailed explanation-4: -Therapeutic cloning uses enucleated human eggs and somatic cell nuclear transfer technology to create a human embryo that is a genetic clone of the patient. The embryo is destroyed to obtain embryonic stem cells that have the same genotype as the patient.
