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 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.
Sequence of bases in a DNA molecule which codes for the sequence of amino acids in a protein. Each group of three bases, codes for an amino acid.
The complete sequence of all 20,000-25,000 human genes. That is, which chromosomes they are in and whereabouts the gene appears on that chromosome's piece of DNA.
Cells which can divide repeatedly without becoming differentiated and have the capacity to develop into a diverse range of specialised cell types.
A list of often difficult or specialised words with their definitions.
Knowledge of the human genome brings with it enormous power, and also great responsibilities.
