Explain the function of enzymes and how enzymes
can be denatured.

Enzymes are denatured at extremes of temperature and pH. Enzymes are proteins that function as biological catalysts. So, they are molecules that speed up a chemical reaction without being changed by the reaction. Enzymes are folded into complex 3D shapes that allow smaller molecules to fit into them.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
