A role for exon sequences and splice-site proximity in splice-site selection.

abstract：:Murine intracisternal A particles have a number of properties which are common to known RNA tumor viruses, but horizontal transmission has not been previously demonstrated. The apparent absence of infectivity may be related to the failure of these particles to be released from cisternae of endo-plasmic reticulum. Prev...
