Nonrandom Dimerization of Murine Leukemia Virus Genomic RNAs
26 Oct 2004
Abstract excerpt
Retroviral genomes consist of two unspliced RNAs linked noncovalently in a dimer. Although these two RNAs are generally identical, two different RNAs can be copackaged when virions are produced by coinfected cells. It has been assumed, but not tested, that copackaging results from random RNA associations in the cytoplasm to yield encapsidated RNA homodimers and heterodimers in Hardy-Weinberg proportions. Here,...
