What makes the new techniques called "somatic cell nuclear transfer" appealing to doctors ?

This is because through this technique;

The Somatic Cell Nuclear Transfer technique has the potential to be used to reproduce extinct species.

Explanation:

Somatic cell nuclear transfer (SCNT) involves the nucleus from a somatic body cell being transferred to the cytoplasm of an enucleated egg (an egg that has had its own nucleus removed). Once the somatic nucleus is inside the egg it is reprogrammed by egg cytoplasmic factors to become a fertilized egg (zygote) nucleus. The egg is allowed to develop to the blastocyst stage where embryonic stem cells can be created from the inner cell mass of the blastocyst. Mouse, monkey and human embryonic stem cells have been made using SCNT.

Reproductive cloning occurs by implanting a SCNT derived blastocyst into the uterus of a surrogate mother, where the embryo develops into a fetus.

The SCNT technique was used to create the first cloned mammal, Dolly the sheep.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
