Genes are already made out of DNA or RNA. You can find a gene in a chromosome and this will be responsible for making sure that certain traits are passed on from one generation to another. For example, if a couple is both blue-eyed, they are likely to have a child who also has this trait because this will be passed on through their genes.
DNA, on the other hand, is considered to be complex items that will make up nucleotides. If you are not familiar with nucleotides, these are simple monomer units. Without all of these things, traits will be harder to pass on from one generation to another.
