Active site
Region of enzyme where substrate binds
Chromosome
Strand of DNA containing genes
Denature
Shape of an enzyme is changed so that it can no longer catalyse a reaction
DNA
Biological polymer made from nucleotide monomers. The sequence contains all the information needed to make an organism
DNA base
Nitrogenous base found in DNA - adenine, thymine, cytosine or guanine
Enzyme
Biological catalyst - this means it speeds up reactions without being used up
Gene
Section of DNA which codes for a characteristic
Lock and key hypothesis
Model that explains the specificity of enzymes
Nucleotides
Monomer (unit) found in DNA, consisting of an organic base, ribose sugar and a phosphate group
Polymer
Substance made up of many monomers (similar subunits) bonded together
Substrate
Molecules that an enzyme acts upon
