Which statement defines cloning?

Which statement defines cloning?

• A. A general term for the research activity that creates a copy of some biological entity (a gene or organism or cell)
• B. Making a genetically identical copy of DNA or of an organism
• C. A process in which a cell, cell product, or organism is copied from an original source
• D. The deliberate creation of an identical copy of an organism or cell

Answer: (A)

Cloning is an umbrella term for the research activities that create copies of biological entities, whether it's a gene, a cell, or an entire organism. This broad framing matters because cloning encompasses different methods and targets, from copying DNA fragments in molecular cloning to producing genetically identical organisms, as well as duplicating cells or cell products. That inclusive scope is what makes the statement the best definition; it acknowledges that cloning isn't limited to one specific item or a single procedure. The other options are narrower or describe cloning in a way that misses this breadth—for example, focusing only on DNA or only on a whole organism, or describing cloning as a single process.
