What is Cloning?
Within Biology, which covers cells, the human body, genetics, evolution, plants and ecosystems: the science of living things, this topic explains Cloning. Biology topics show how living things work, from the cell up to whole ecosystems, with models you can explore step by step.
Check that you can explain Cloning in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Cloning helps you explain how living things stay alive and respond to their surroundings, which is central to biology exams.
Cloning in detail
A clone is a genetically identical copy of an organism. Plants can be cloned by taking cuttings or by tissue culture, in which small pieces of tissue are grown on a sterile medium containing nutrients and hormones, producing many identical plants quickly.
Animals can be cloned by embryo transplants, splitting an embryo into several, or by adult cell cloning, in which the nucleus from an adult body cell is placed into an egg cell with its nucleus removed, as with Dolly the sheep. Clones lack variation, so they are vulnerable to the same disease. Human cloning raises ethical questions.
How the interactive helps you understand Cloning
Watch the cell model in the interactive. Use any sliders or buttons it offers to change the values and see how the cell model responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Cloning.
Real-life uses and examples
- Use Cloning to interpret a diagram, graph or microscope image from a practical.
- Structure a longer answer about Cloning by moving from definition to example to consequence.
- Explain how Cloning helps a living thing stay alive, using a plant or animal example.
Common mistakes to avoid
- Using everyday words, such as “energy” or “bad”, without their scientific meaning.
- Listing the steps of a process without saying how one step causes the next.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
