1Y99, 462D - PubMed Abstract: 
An important step in retroviral replication is dimerization of the genomic RNA prior to encapsidation. Dimerization is initiated by the formation of a transient 'kissing-loop complex' that is thought to be subsequently matured into an extended duplex by the nucleocapsid protein (NCp) ...
