    Summary
    This summary is machine-generated.

    The study demonstrates that streptomycin cations increase the solubility of highly polymerized RNA, similar to how a cellulose interface affects RNA distribution. This finding explains RNA infectivity preservation in viral complexes.

    Main Results:

    • An increase in the solubility of RNA complexed with streptomycin cations was observed.
    • A direct analogy was demonstrated between this solubility increase and the effect of a cellulose/solution interface on RNA distribution.
    • The findings support the mechanism for preserving viral RNA infectivity.

    Conclusions:

    • Streptomycin cations enhance the solubility of highly polymerized RNA.
    • The cellulose/solution interface influences RNA distribution, mirroring streptomycin's effect.
    • This research provides insights into RNA complex stability and infectivity.
