Proteins in turn are the (cid:271)uildi(cid:374)g (cid:271)lo(cid:272)ks of (cid:272)ells as the (cid:396)egulato(cid:396)s that di(cid:396)e(cid:272)t the (cid:271)od(cid:455)"s p(cid:396)o(cid:272)esses: mitosis, forms all other cells, the (cid:272)ell"s (cid:374)u(cid:272)leus, i(cid:374)(cid:272)ludi(cid:374)g the (cid:272)h(cid:396)o(cid:373)oso(cid:373)es, dupli(cid:272)ates itself a(cid:374)d the (cid:272)ell divides.
