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.
Genetic engineering involves changing the DNA of an organism, usually by deleting, inserting or editing a gene to produce desired characteristics.
The use of biological organisms or enzymes to create, break down or transform a material.
Deoxyribonucleic acid. This is the molecule which contains the genetic code. It coils up tightly inside chromosomes. DNA is a double helix made from two strands which are joined together by pairs of bases.
This technology exists - it is the polymerase chain reaction.
Like all brilliant ideas, the polymerase chain reaction is incredibly simple yet extremely clever at the same time. This resource provides details of the reaction and its uses.
