mRNA activity of a Sindbis virus defective-interfering RNA.
We obtained Sindbis defective-interfering particles by nine and undiluted passages of standard virus on chicken embryo fibroblasts. These particles contain a deleted 20S RNA molecule which has mRNA activity, as shown by translation in cell-free systems in vitro. In infected cells, this mRNA activity appeared to be totally inhibited except at very late times postinfection.
