Question

question 34
a clear distinction between therapeutic cloning and reproductive cloning is that

the embryo is implanted into a surrogate mother in therapeutic cloning
embryonic stem cells are harvested from the early embryo in therapeutic cloning
reproductive cloning involves the use of other species cells for humans, whereas therapeutic cloning does not
therapeutic cloning involves the production of an adult individual that is identical to that of the donor cell

Explanation:

Therapeutic cloning aims to produce cells or tissues for medical treatment. Reproductive cloning aims to create a new individual. The key difference is that in reproductive cloning, the embryo is implanted into a surrogate mother to develop into a full - fledged individual, while in therapeutic cloning, it is not.

Answer:

The embryo is implanted into a surrogate mother in therapeutic cloning (Incorrect. This is the case for reproductive cloning). Embryonic stem cells are harvested from the early embryo in therapeutic cloning (Part of the process in therapeutic cloning but not the main distinction). Reproductive cloning involves the use of other species' cells for humans, whereas therapeutic cloning does not (Incorrect. Both usually use human cells). Therapeutic cloning involves the production of an adult individual that is identical to that of the donor cell (Incorrect. This is reproductive cloning). The correct distinction is that in reproductive cloning, the embryo is implanted into a surrogate mother to develop into a new individual, while in therapeutic cloning, it is not. But among the given options, none is completely accurate. If we assume the intended correct answer is based on the embryo implantation aspect (even if the option description is a bit off), the answer is “The embryo is implanted into a surrogate mother in therapeutic cloning” (but this option has a wrong statement. If we consider the reverse - reproductive cloning implants the embryo, therapeutic does not. But since the options are as given, if we have to choose the one that relates to the embryo implantation concept (even with wrong labelling in the option), we might have to go with that option).
