This interaction was studied by gel retardation and UV Lysates were prepared from the virus peak fractions (pcross-linking assays using an RNA probe containing the lysate) and from the gradient bottom fractions (b-lysate; 69-nt Ps and the N protein from MHV-A59 infected cell negative control). A structural model for coronaviruses was flanked by non-MHV sequences could confer specific proposed, in which a spherical core, composed of a combination of N and M proteins, was present in addition to encapsidation to a heterologous RNA in MHV infected INTERACTION BETWEEN NUCLEOCAPSID PROTEIN AND PACKAGING SIGNAL of a murine coronavirus in the absence of helper virus.	./cache/cord-271526-14nfqusv.txt	./txt/cord-271526-14nfqusv.txt
