Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Making an identical copy of a cell or tissue is
A
genetic transformation
B
stem cell diffusion
C
reproductive cloning
D
therapeutic cloning
Explanation: 

Detailed explanation-1: -Therapeutic cloning is the transfer of nuclear material isolated from a somatic cell into an enucleated oocyte in the goal of deriving embryonic cell lines with the same genome as the nuclear donor.

Detailed explanation-2: -For example, cardiomyocytes could be used to treat patients with hearth disease, pancreatic islet cells, for patients with diabetes, or hepatocytes, in a tissue-engineered liver. The main purpose of embryonic stem cell cloning techniques would be to create tissue that would not be subject to graft rejection.

Detailed explanation-3: -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-4: -Therapeutic Cloning involves 2 cells (egg and other) to create stem cells to heal damaged cells and illnesses. Non-Therapeutic Cloning involves a similar process, but for the intent of stem cell research. The process uses substitution to create stem cells which can then be inserted to the patient.
