Ka taea te whakarōpū i ngā huaketo i runga anō i te pūtau kaihautū e pāngia ana e rātou: huaketo kararehe, huaketo tipu, huaketo pūngāwerewere, me ngā huaketo bacteriophages (huaketo e pāngia ana e te huaketo, e ngā te huaketo tino matatini). Ka whakamahia e tētahi atu whakarōpūtanga te āhua āhuahanga o to ratou capsid (he maha he he hēlika, he icosahedron) ranei te hanganga o te huaketo (hei tauira, te aroaro, te kore ranei o te taupoki lipid). ngā huaketo i roto i te whānuitanga rahi i te pā ana ki 30 nm ki te pā ana ki 450 nm, e te tikanga e kore e taea te kite i te nuinga o ratou ki te microscopes marama. Kua ako te āhua me te hanganga o huaketo i te microscopy hiko, NMR spectroscopy, me te X-ray crystallography. Pātai: He aha te rahi o huaketo?
30 nm ki te āhua 450 nm
