<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Isethulo: Njenge - DNA, i - RNA ingakwazi ukuthwala ukwaziswa kofuzo. Amagciwane e - RNA anezakhi zofuzo ezakhiwe nge - RNA ebhala amakhodi amaprotheni amaningana. I-genome yegciwane iphindaphindeka ngamanye alawo maphrotheni, kuyilapho amanye amaprotheni evikela i-genome njengoba inhlayiya yegciwane ihamba iye esitokisini esisha. Ama-viroid elinye iqembu lezinto ezibangela izifo, kodwa aqukethe i-RNA kuphela, awanamakhodi amaprotheni futhi aphindaphindwa yi-polymerase yeseli yesitshalo. Umbuzo: Ngaphandle kwe - DNA, yini enye ekwazi ukudlulisela ukwaziswa kofuzo?  <response>: I-RNA
