Concept:
Cloning is a biotechnological process of producing genetically identical organisms. The most significant breakthrough in cloning history was the successful creation of
Dolly the sheep, the first mammal cloned from an adult somatic cell using the technique known as
Somatic Cell Nuclear Transfer (SCNT).
Step 1: Identifying the experiment
Dolly the sheep was born on
5 July 1996 at the
Roslin Institute, Scotland. The experiment demonstrated that a fully differentiated adult cell nucleus can be reprogrammed to develop into a complete organism.
Step 2: Scientists involved
The research was led by:
• Sir Ian Wilmut
• Keith Campbell
These scientists successfully cloned Dolly, proving that adult somatic cells retain full genetic potential.
Step 3: Eliminating incorrect options
• Watson and Crick: Discovered DNA structure (1953), unrelated to cloning.
• Watson (in other options): Not involved in Dolly’s cloning experiment.
Hence, only Wilmut and Campbell are correct.
