Polymerase chain reaction
PCR is a series of temperature-controlled reactions which enable us to amplify a very tiny sample of DNA, producing enough material for it to be analysed or used in DNA profiling.
Genetic engineering
Genetic engineering involves changing the DNA of an organism, usually by deleting, inserting or editing a gene to produce desired characteristics.
Biotechnology
The use of biological organisms or enzymes to create, break down or transform a material.
Stem cell
Cells which can divide repeatedly without becoming differentiated and have the capacity to develop into a diverse range of specialised cell types.
Glossary
A list of often difficult or specialised words with their definitions.
Cloning
Reflect on the fact that cloning plants has been done for years.
Understand that there are different types of cloning, using different techniques and producing different outcomes.
Think about the implications of cloning technology on the future of medical treatment.
Consider the ethics of cloning.
