There are 20,000 to 25,000 genes - either active (expressed) or inactive. Genes: small segments of giant dna molecules (form the words of those chapters) Environmental events turn on genes - then genes provide the code for creating protein mols (cid:1372) (cid:271)ody"s (cid:271)uildi(cid:374)g (cid:271)lo(cid:272)ks.
