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.
Cells which can divide repeatedly without becoming differentiated and have the capacity to develop into a diverse range of specialised cell types.
The use of biological organisms or enzymes to create, break down or transform a material.
This resource will help you to:
A short piece of DNA which is responsible for the inheritance of a particular characteristic. It codes for the production of a specific protein. Genes occupy a fixed position, called a locus, on a particular DNA molecule.
Genetic engineering provides the key to unlock possibilities as yet unimagined.
