Q: Which process was used to clone Dolly the sheep?

Dolly was cloned using a process called Somatic cell nuclear transfer. The process involved transplanting nuclei from adult cells into oocytes or blastocysts and allowing them to grow and differentiate, producing pluripotent cells.

Q: When was the first cloned puppy ‘born’?

Snuppy ‘born’ on April 24, 2005, was an Afghan hound, the first dog clone. The puppy was created using a cell from an ear from an adult Afghan hound and involved 123 surrogate mothers.

Q: What is a common source of donor cells in therapeutic cloning experiments?

Therapeutic cloning involves creating a cloned embryo for the sole purpose of producing embryonic stem cells with the same DNA as the donor cell. The richest source of embryonic stem cells is tissue formed during the first five days after a fertilised egg has started to divide. At this stage of development, the clump of cells are called the blastocyst.

Q: Who coined the term ‘clone’?

In 1903, plant physiologist Herbert J. Webber coined the term “clone,” from the Greek klon, to refer to the technique of propagating new plants using cuttings, bulbs or buds.
