made of DNA molecules that contain the
genes. - 4DNA (deoxyribonucleic acid)a
complex molecule containing the
genetic information that makes up the
chromosomes. - 5genesthe biochemical units of heredity
that make up the chromosomes; segments
of DNA capable of synthesizing proteins. - 6genomethe complete instructions for
