DNA Replication and Their Enzymes

DNA is:

• A molecule on which a substrate acts

• A substance that speeds up a chemical reaction

• A self replicating molecule

• A type of cell division

Organic compound that is the basic building block of nucleic acids

• DNA

• RNA

• Nucleotide

• Catalyst

A substance produced by a living organism which acts to bring about a specific biochemical reaction

• Protein

• RNA

• Nucleotide

• Enzyme

A compound molecule made of many repeating units

• Polymer
