Well everything is made of complex proteins. There isn't one single organism just comprised of proteins. For example keratin is a protein that is made when RNA passes through a ribosome.

Genes come in different varieties, called alleles<span>. </span>Somatic cells<span> contain two alleles for every gene, with one allele provided by each parent of an organism. It is impossible to tell exactly what gene the organism could have. </span>
