Translation of infectious bronchitis virus RNA 2006-03-27 .txt text/plain 1125 72 63 When RNA extracted from IBV-infected and uninfected chick embryo kidney cells was added to the reticulocyte system there was a stimulation of methionine incorporation (Table 1 ) and a whole spectrum of polypeptides could be found in the product (Fig. la) . It has a molecular weight of 55 000, co-migrates with one of the bands formed by translation of the virion RNA and is also present in the IBV capsid. When the products formed in the wheat germ synthesis by IBV infected cellular RNA were compared with those formed by uninfected cellular RNA, two new bands could be identified, with molecular weights Lomniczi [4] have demonstrated that the RNA is infectious and that the virion does not contain any transcriptase activity (Lomniczi, unpublished results) . In the reticulocyte system one of the products formed by the virion RNA appears to have the same molecular weight as one of the virion proteins. ./cache/cord-015606-h9bbvpzd.txt ./txt/cord-015606-h9bbvpzd.txt
